Why We Keep Having the Same Fight?

Answering: why do we keep having the same fight? A psychobiological view of the two-person system (article by Anna Keyter)

Couple therapy can help. The harder question is why good work still stalls when the room heats up. In a two-day PESI workshop, Stan Tatkin put that problem at the centre of a Psychobiological Approach to Couple Therapy (PACT): under relational stress, partners can lose access to the capacities they demonstrate when calm. The issue is not always motivation, insight, or a missing communication script. It is whether the couple can still use what they know when it matters most.

A relationship is a team sport. Teams do not wait for game day to invent the playbook. They agree the purpose, rehearse the moves, and practise under conditions that resemble live play. Couples need the same thing. Insight in a quiet session is not the same as performance under threat.

Why we keep having the same fight? Monkey see, monkey do

A lot of the playbook was written before this relationship began. Children learn how a two-person system works by watching the adults in charge of them. Tone, timing, who gets protected, who gets dropped, how repair happens — or does not. That is monkey see, monkey do. Not a sentence about destiny. A sentence about modelling.

Happy parents, happy kids is the other side of the same point. Children do not only inherit genes. They live inside the weather of the adult team. When the two people running the house work with each other rather than against each other, the child’s nervous system has a safer base. When the adult team is not in good order, the child learns that love and threat can arrive in the same room.

Development shapes capacity. It does not write the ending. Early learning, later relationships, the present partner, culture and present stress all still matter. The clinical question is not “Whose childhood is to blame?” It is “What sequence is running now — and can this team learn a different one?”

The ring of the bell

If the system is not in good order, it becomes like the ring of a bell. People respond to the ring. A look, a sigh, a late text, a particular silence — and the old sequence starts before anyone has chosen it. Cue, protective move, partner response, escalation or withdrawal, incomplete repair. The content of the fight can change. The sequence often does not.

That is why “we know this already” fails. The bell does not ask whether you have insight. It asks which response has been practised enough to fire under load. Under stress, the brain reprioritises. Working memory and perspective narrow. Habit stays. The couple is not ignorant. They are answering a cue that has been paired with danger, abandonment or humiliation for a long time.

Working with each other, not against each other, means noticing the bell and refusing to let it run the whole play. The team’s job is to hear the ring and use a pre-agreed move: signal, slow, protect, repair. If you wait to become a better person after the bell has already rung, you are asking thought to outrun a practised reflex. We all respond to trauma in our own ways. We may be triggered by something happening for us in a specific moment that could be ‘our ring of the bell’.

Knowing better is not doing better

Why we keep having the same fight in relationships even when we think we know better. Partners often arrive able to describe their pattern with painful accuracy. Then the same sequence happens again. Acute stress can narrow working memory, flexible attention, perspective-taking and impulse control. Habitual protection stays available. Rehearsed responses stay available. Complex new learning does not reliably come online.

That is why a purely cognitive plan can fail in the moment it is needed. Cognitive-behavioural tools are not useless. They can be very useful when both people have enough state to use them. The limitation is transfer. Skills learned in a regulated office do not automatically appear in a 10 p.m. kitchen argument. If therapy only trains the couple in calm conditions, it trains a version of them that is not present when the system is under load.

Watch the live system, not only the story

PACT treats the relationship as the treatment unit. What partners do to each other in the room is primary data. Stories still matter. They are not enough. Communication is often necessary and still not sufficient, because under sufficient stress the window for language and fairness shrinks.

Adult attachment is part of that picture, but it is not a box to drop people into. Pursuit and withdrawal are moves, not identities. Each move becomes the next signal. The other nervous system answers. The loop tightens.

High mobilisation can look like volume, interruption, urgency and a narrowed topic. Quiet can look like calm and still be shutdown, fear, fatigue, strategy or cultural reserve. The body offers data. It does not hand anyone a finished diagnosis. Ask before you infer.

How to train the team under stress to understand why we keep having the same fight

This was the part that matters most. The workshop was a conceptual introduction, not a licence to run proprietary PACT protocols. The usable stance is still clear: design the system while people can think, then rehearse the version of the couple that appears when the bell rings.

1. Design the team before game day

Agree the rules while both people can still think.

1. What is this relationship for?
2. Which decisions need both people?
3. How will we handle work, family, phones, friends — the “thirds”?
4. What do we do in the first 30 seconds after the bell rings?

Why we keep having the same fight when under stress? You reach for a pre-agreed play: signal rather than ambush, slow down, protect dignity, use the guardrail you already named. Work with each other, not against each other.

2. Practise the real sequence, not a calm speech

If the brain narrows under stress, train the version of the couple that appears under stress.

1. Pick one recurring loop, not the whole relationship.
2. Keep the task small and consented.
3. Let enough heat in to hear the bell and still choose.
4. Stop if someone loses choice, orientation or safety.
5. Debrief: what changed in face, voice, timing, and what each person can try next time.

A new sentence in a quiet session is homework. A new move while the pattern is live is training. Monkey see, monkey do works in therapy too: the couple needs to watch themselves run a different play, not only talk about one.

3. When stress hits, reduce the task

Do not add insight when capacity has dropped.

1. Slow the pace.
2. Shorten the question.
3. One topic.
4. Sit or stand so both can see each other.
5. Ask for a yes/no or a limit (“I need two minutes”) rather than a full explanation.
6. Postpone meaning-making until both can track the other person.

If working memory is busy with threat, analysis will bounce. Regulation first, meaning second.

4. Repair fast, then change the condition

Conflict is not the failure. Incomplete repair is. Incomplete repair is also what teaches the child that the house cannot recover.

1. Notice the moment the team is taking damage.
2. Stop the move that is making it worse.
3. Name impact without putting the other person on trial.
4. Restore contact, dignity and choice.
5. Update the agreement so the same hole is not left open.

An apology with no change in conditions is not repair. The next ring of the bell will find the same hole.

5. Watch the listener, not only the speaker

The receiving partner often shifts first: gaze, breath, posture, latency. That shift is often the bell.

A usable line: “I noticed that change. What was happening for you?”
Describe the cue. Do not announce a nervous-system diagnosis.

6. Treat pursuit and withdrawal as moves, not identities

Track function:

1. Is this bid trying to get contact, or to control?
2. Is this distance trying to regulate, or to abandon?
3. What does the other person’s response then confirm?

Then ask the sequence: What activated it? How was distress signalled? How was that signal read? What settled or escalated it? Can either person use new evidence?

7. Know when to stop

Push when a harmful loop is running and both people still have choice. Stop when there is coercion, loss of consent, severe impairment, or the work is outside your competence. Pro-relationship never means staying in an unsafe system. Happy parents, happy kids does not mean silent parents, hidden kids.

Secure functioning is behaviour under pressure

Secure functioning is not the same as a secure attachment history. A difficult childhood does not sentence a couple. A lucky childhood does not automatically produce fairness when the bell rings. The treatment direction is observable: both minds matter, harm is repaired, power is shared, thirds are handled in the open, and the couple cooperates when it would be easier to win.

That is the team-sport point. Relationship design beats improvisation under stress. Pro-relationship is not self-erasure, compulsory closeness, or endurance of abuse. A team that requires one player to absorb all the harm is not a team — and it is not a safe climate for children either.

The point of the work to answer why we keep having the same fight

Couple therapy does not fail because partners never learned the right sentence. It often fails because the sentence was trained for a nervous system that is not available at midnight. Stress reprioritises the brain. The bell rings. The old play runs. That is why rehearsal under realistic conditions matters more than another insight about childhood.

Treat the relationship as a two-person team. Agree the principles while both people can still think. Practise the plays before game day. Work with each other, not against each other. Then, when the bell rings, you are not asking love to improvise what the system was never trained to do.
