How can I get my partner to do more in our relationship?..

The Overfunctioner–Underfunctioner Dynamic: Why It Can Happen (Especially in Neurodivergent Relationships) and How to Make Change

Every relationship has an operating system.

Most couples never notice it until it stops working.

One person remembers birthdays. The other assumes birthdays are remembered. One partner notices the groceries are running low. The other trusts they will appear. One person keeps track of school forms, vet appointments, Medicare claims, whose parents have been visited recently and whether there's milk for tomorrow morning.

None of these moments seem particularly important on their own. Yet over months and years they begin to accumulate. Gradually, one person's mind becomes responsible not simply for doing more, but for noticing more.

This difference matters.

People often describe this experience by saying they feel like the 'parent' in the relationship. Others describe constantly feeling as though they're being reminded, corrected or disappointing their partner despite genuinely wanting to contribute. Both experiences are painful. Both are understandable. And both are usually symptoms of the same underlying relationship pattern rather than evidence that one person is inherently responsible and the other inherently careless.

Psychologists sometimes describe this as an overfunctioner–underfunctioner dynamic. I prefer to think of it more simply: a relationship that has gradually concentrated responsibility into one person's mind.

That distinction changes the conversation. Instead of asking, 'Who's the problem?', we begin asking, 'How did our relationship organise itself this way?'

This perspective is particularly valuable in neurodivergent relationships. ADHD, autism and other neurodevelopmental differences influence executive functioning, communication and sensory experiences, but they do not automatically determine who carries the relationship. Two couples can face similar neurological challenges and develop entirely different patterns depending on how they adapt together.

What Is the Overfunctioner/Underfunctioner Dynamic?

Overfunctioning is often misunderstood as simply 'doing more'. In reality, it involves taking increasing responsibility for the functioning of the relationship itself. An overfunctioning partner often becomes the organiser, planner, reminder, emotional regulator and problem solver. They carry the invisible responsibility of noticing what needs doing before anyone else does.

Underfunctioning is equally misunderstood. It is rarely a sign that someone does not care. More often it reflects a combination of overwhelm, reduced confidence, executive functioning differences, avoidance of criticism or a relationship that has slowly taught one partner that someone else will eventually take over.

These roles are not fixed identities. They are positions people gradually occupy within a relationship system. The more one person steps forward to carry uncertainty, the fewer opportunities the other has to step into responsibility. Likewise, the more one partner withdraws, the more pressure the other feels to compensate.

This reciprocal process is why assigning blame rarely creates change. It explains the past, but it does not redesign the future.

How These Roles Develop

Very few couples begin their relationship with an agreement that one person will manage life while the other follows along. These roles develop through hundreds of small adaptations.

Sometimes anxiety sits at the centre. Completing the task yourself feels quicker than waiting. Sometimes perfectionism is involved. It genuinely feels easier to do it 'properly' than explain it. Sometimes shame is the driver. After enough corrections, a partner may stop taking initiative because trying has become emotionally risky.

One helpful way to picture this is to imagine an empty space whenever a new responsibility appears. Someone eventually steps into that space. If one partner experiences greater discomfort with uncertainty, they are more likely to act first. The task disappears, both people feel temporary relief and the relationship quietly learns who usually carries uncertainty.

Over time, competence itself becomes part of the problem. Highly capable people attract more responsibility. Meanwhile, confidence grows through opportunities to solve problems independently. When those opportunities disappear, confidence often shrinks with them.

The goal of understanding this pattern is not to decide who is right. It is to recognise that both people have adapted to a system that once made life easier but may now be limiting both partners in different ways.

The Invisible Work

One of the reasons this pattern is so difficult to recognise is that much of the imbalance is invisible. Most couples can identify who empties the dishwasher or walks the dog. Far fewer can identify who remembers that the dishwasher needs emptying, notices the dog is due for vaccinations or anticipates that tomorrow's lunches still need to be packed.

This distinction between doing the work and carrying the work is crucial. The mental load refers to the invisible cognitive labour involved in anticipating, planning, organising and remembering. Emotional labour involves monitoring the emotional climate of the relationship, smoothing conflict, remembering important conversations and noticing when someone needs support.

Many overfunctioners describe feeling exhausted long before the day has even begun. They are not only completing tasks; they are continually scanning for what might need attention next. Their nervous system rarely receives permission to switch off because there is always another detail waiting to be noticed.

Thinking About Responsibility Differently

It can be helpful to picture responsibility as something that naturally flows towards the person who is least comfortable leaving uncertainty unresolved.

Imagine an unpaid bill sitting on the kitchen bench. Both partners can see it. One feels a rising sense of urgency and pays it immediately. The other assumes there is still time or becomes distracted by competing demands. Neither response necessarily reflects how much they care. It reflects differences in how their brains respond to unfinished tasks.

Each time the first partner resolves the uncertainty, both people experience relief. The bill disappears. Life continues. Yet the relationship has quietly learned who usually absorbs uncertainty. Today's efficient solution slowly becomes tomorrow's expectation.

The Competence Paradox

Highly capable people often become victims of their own competence. The more reliably someone notices, plans and solves problems, the more likely others are to rely on those strengths. Responsibility accumulates around the person who appears most capable.

At the same time, confidence grows through experience. Psychologists describe this as self-efficacy: the belief that we can successfully manage life's challenges. Self-efficacy develops when people have opportunities to try, make mistakes, adapt and eventually succeed.

When one partner consistently steps in before the other has that opportunity, an unintended message can emerge: 'I've got this.' Over time, the message can become: 'Maybe you can't.'

Neither message is usually intentional. Both can reshape how partners see themselves.

The aim is not to stop helping one another. Healthy relationships depend on support. The challenge is recognising when support quietly shifts into carrying responsibility on someone else's behalf. Support increases capacity. Carrying replaces it.

The Neurodivergent Layer

This dynamic often becomes more complex when one or both partners are neurodivergent. ADHD, autism and other neurodevelopmental differences can influence planning, communication, attention, sensory processing and emotional regulation. These differences deserve understanding, but they do not automatically determine who becomes the overfunctioner or underfunctioner.

The more useful question is not 'Does ADHD cause this?' but 'How has our relationship adapted to the challenges we experience together?' Two couples may experience similar executive functioning differences yet develop entirely different relationship patterns depending on how they respond.

ADHD and Shared Responsibility

For many people with ADHD, remembering future tasks, estimating time, initiating activities and maintaining routines require significantly more effort. From the outside, these differences can look like carelessness or lack of motivation when they are better understood as differences in executive functioning.

When these challenges appear repeatedly, many partners naturally begin compensating. They send reminders, organise appointments or quietly complete forgotten tasks. Initially this can be supportive. Over time, however, one person's brain can become responsible for managing both people's responsibilities.

The goal is not to expect someone with ADHD to 'try harder'. It is to build external systems that reduce the need for either partner to rely solely on memory. Shared calendars, visual reminders, automation, body doubling and explicit planning conversations all increase participation without concentrating responsibility in one person.

Autism and Invisible Cognitive Load

Autistic experiences are equally varied. Some autistic people create highly organised routines because predictability reduces stress. Others expend so much energy managing sensory input, social expectations and daily transitions that very little executive functioning remains for household administration.

Differences in communication can also shape this pattern. One partner may assume responsibilities should be discussed explicitly, while the other expects important tasks to be noticed automatically. Neither approach is wrong; they simply reflect different assumptions about how relationships work.

Justice sensitivity, monotropism and fluctuating capacity can further influence how responsibilities are experienced. On some days, a task that seems simple from the outside may require considerable cognitive effort because of competing sensory or emotional demands.

A Fictional Couple

Let's imagine a fictional couple.

Emma has ADHD. Josh does not.

Emma forgets to book the dentist despite intending to do it several times. Josh notices the appointment still hasn't been made and books it himself. Months later, Josh manages every appointment, bill and deadline. Emma feels guilty that she keeps letting him down. Josh feels exhausted and increasingly believes that if he stops managing everything, life will fall apart.

The problem is not Emma's ADHD alone. Nor is it Josh's willingness to help. The relationship has gradually adapted by placing more and more responsibility into Josh's mind.

Now imagine a different response. Instead of Josh becoming the reminder, they create a shared digital calendar with recurring reminders, automated bookings where possible and a weekly planning check-in. Emma remains responsible for organising her appointments, but the system supports her executive functioning rather than replacing it.

The difference is subtle yet profound. Responsibility remains shared even though support is provided.

How Both Partners Maintain the Pattern

Once couples recognise this dynamic, the first question is often, 'So whose fault is it?'

It is an understandable question, but rarely the most helpful one. By the time this pattern has become established, it is usually maintained by both partners in different ways. The overfunctioning partner often steps in because uncertainty feels uncomfortable. The underfunctioning partner may hesitate because uncertainty, shame or repeated correction has reduced their confidence.

Neither response is irrational. Each makes sense in the context of the relationship that has developed. Ironically, each also reinforces the other.

The Confidence Gap

Confidence is built through repeated experiences of solving problems. Every time we navigate a challenge successfully, our brain collects evidence that we are capable.

When one partner repeatedly takes over before the other has an opportunity to struggle, adapt and succeed, that evidence is never collected. Gradually, two different internal stories emerge.

The overfunctioning partner begins believing, 'If I don't do it, no one will.'

The underfunctioning partner begins believing, 'They'll probably need to redo it anyway.'

Neither belief appears overnight. They evolve quietly through hundreds of ordinary interactions.

The Identity Trap

Perhaps the greatest danger is that behaviours slowly become identities.

'I organised the bills' becomes 'I'm the organised one.'

'I forgot to pay the registration' becomes 'I'm hopeless with paperwork.'

Once identities become established, change feels surprisingly difficult because new behaviour appears to contradict who someone believes they are.

Healthy relationships allow identities to remain flexible. A person can be organised in one season of life and overwhelmed in another. Someone who once relied heavily on their partner can develop confidence when given the opportunity and support to do so.

Therapy often involves helping couples move away from identity language and back towards describing patterns of behaviour. Patterns can be redesigned. Identities tend to feel fixed.

Another Fictional Example

Imagine another fictional couple, Hannah and Priya. Following the birth of their first child, Hannah gradually takes responsibility for feeding schedules, medical appointments and household planning while Priya returns to long work hours. Neither notices the shift at first. Two years later Hannah feels invisible, while Priya feels constantly criticised.

Neither partner intended to create a parent–child dynamic. They simply adapted to a demanding life stage. Recognising this allows them to ask a different question: not 'Who has failed?', but 'What systems helped us survive that season, and what systems do we need now?'

Moving Towards Partnership Again

Understanding the pattern is only the beginning. Awareness creates possibility, but change happens through repeated experiences of doing something differently.

The aim is not for both partners to contribute in identical ways. Healthy relationships rarely look perfectly equal. Instead, they are characterised by shared ownership. Ownership means responsibility genuinely belongs to someone rather than one partner quietly supervising, reminding or monitoring the other.

A helpful question is: 'How can we design our relationship so that success depends less on memory and more on good systems?' This shifts the focus from individual shortcomings to collaborative problem solving.

Building Systems Instead of Heroes

Many relationships rely heavily on one exceptional person. They know every password, remember every appointment and carry every invisible responsibility. While this may keep life running smoothly in the short term, it creates vulnerability in the long term.

Strong relationships are supported by systems rather than extraordinary individuals. Shared calendars, automated payments, visual reminders, planning meetings and clearly owned responsibilities reduce the pressure on any one person's brain.

Rather than asking one partner to become more organised, couples can ask how the environment can better support both people.

Support Versus Rescue

Support increases another person's capacity. Rescue replaces it.

Support might involve brainstorming strategies together, using technology, sharing information or adjusting expectations during periods of burnout or illness.

Rescue often sounds like, 'I'll just do it.'

Sometimes rescue is necessary. During acute stress, illness or crisis, relationships naturally become more flexible. Difficulties arise when temporary rescue quietly becomes the default way of functioning.

One useful reflection is: 'If we continue doing this for the next five years, will both of us become more capable or will one of us become increasingly responsible?'

When Life Changes

Many couples notice this pattern emerging after significant life events such as becoming parents, moving house, experiencing burnout, caring for ageing parents, navigating chronic illness or receiving an ADHD or autism diagnosis.

Relationships are adaptive systems. They reorganise in response to changing demands. The challenge is ensuring that adaptations which were once helpful do not become permanent identities.

Periods of stress call for flexibility. Periods of stability provide an opportunity to review how responsibilities are shared and whether the current arrangement still reflects both partners' values, strengths and capacities.

When Therapy Can Help

Some couples recognise themselves in every section of this article yet still struggle to change. That is not a sign of failure. Patterns that have developed over years are difficult to interrupt because they become automatic.

Couples therapy is not about deciding who is right or assigning blame. It is about slowing the interaction down so both partners can see the pattern they have been caught in. From there, they can begin experimenting with different ways of sharing responsibility, communicating expectations and designing systems that fit their unique relationship.

For neurodivergent couples, therapy can also help distinguish between genuine accommodations that support participation and patterns where one partner has gradually become responsible for compensating for the other in ways that are no longer sustainable.

A Final Reflection

At the beginning of this article, I invited you to imagine the person lying awake mentally rehearsing tomorrow. Perhaps you recognised yourself in that image. Or perhaps you recognised the quieter experience of being the partner who feels one step behind, wanting to contribute but never quite managing to meet expectations.

Neither experience makes someone the villain of the story.

More often, they reflect a relationship that has gradually adapted to life's demands in ways that once made sense but no longer serve either person.

The invitation is not for one partner to care less, nor for the other to become perfect. It is to build a relationship where responsibility is shared intentionally, where support increases capability rather than replacing it, and where both people feel trusted to contribute in ways that reflect their strengths, challenges and capacity.

Healthy partnerships are not measured by how much one person can carry. They are measured by how safely both people can put some of the weight down together.

Reflection Exercise

Choose one recurring responsibility in your relationship and discuss it together.

• Who currently notices this task first?
• Who feels responsible if it is not completed?
• What system are you relying on?
• Could a shared system replace one person's memory?
• What would support look like without taking ownership away from the other person?

Small changes made consistently often create far greater shifts than dramatic changes made once.
