How to rebuild trust in relationships after it has been broken

Something happened. Maybe it was a betrayal, a lie discovered, a promise broken in a way that cannot be unsaid. Maybe it was subtler than that: a slow erosion of reliability, a pattern of not showing up, a gradual realisation that the person you trusted was not being straight with you. Either way, the trust is damaged, and now you are standing in the wreckage trying to work out whether it is possible to rebuild, whether it is wise to try, and if so, how you even begin.

Trust research, particularly the work of John and Julie Gottman, offers a framework that is both honest and hopeful. Rebuilding trust is possible, but it is not fast, it is not comfortable, and it requires something from both people that goes beyond apology and forgiveness. This article walks through what the science says about how trust breaks, what it takes to repair it, and how to know whether repair is genuinely underway or just being performed.

What this often feels like

• You want to trust the person again but your body will not let you, there is a vigilance that does not switch off
• You find yourself monitoring for evidence of further betrayal, checking, questioning, reading into small things
• You oscillate between wanting to move forward and feeling a wave of anger or hurt that pulls you back
• You wonder whether your inability to let it go means something is wrong with you rather than the situation
• The person who broke your trust seems to want everything to go back to normal faster than feels possible for you
• You are unsure whether what happened is something that can be repaired or something that should end the relationship

How trust actually works

Trust is not a single thing that exists or does not. The Gottmans describe trust as built through what they call sliding door moments: the hundreds of small, everyday interactions where one person expresses a need and the other either turns toward that need or turns away from it. Did you respond when they reached out? Did you follow through on what you said you would do? Did you choose them over a competing interest in a moment that mattered? Each turning-toward builds a small deposit of trust. Each turning-away makes a small withdrawal.

This means trust is not primarily built through grand gestures. It is built through consistency in small moments. And it breaks the same way. Sometimes trust collapses in a single catastrophic event, an affair, a discovered lie. But more often, the catastrophic event is the final straw in a pattern of accumulated small betrayals: promises not kept, bids for connection ignored, emotional needs dismissed. The big betrayal lands so hard partly because the trust account was already depleted.

Understanding this has practical implications for repair. If trust was eroded gradually, it must be rebuilt gradually. There is no single conversation, no single apology, no single act of contrition that restores what was lost. Repair is a process measured in months and years, not days and weeks. Anyone who tells you otherwise is selling something.

The Gottman ATTUNE model for trust repair

The Gottmans developed the ATTUNE model as a framework for rebuilding trust after betrayal. Each letter represents a component of the repair process. Awareness means the person who broke the trust must develop genuine understanding of the impact of their actions, not as a performance but as an ongoing willingness to sit with the pain they caused. Tolerance means both people must accept that the process will be uncomfortable and nonlinear, that there will be setbacks, triggers, and moments where it feels like no progress has been made.

Turning toward means the betrayer must consistently demonstrate that they are choosing the relationship in the small moments, not just the dramatic ones. Understanding means both people must work to comprehend each other's experience, the betrayed person's pain and hypervigilance, the betrayer's shame and desire to move past it. Non-defensive responding means the person who broke the trust must be able to hear their partner's pain, anger, and fear without becoming defensive, minimising, or turning the focus onto their own discomfort. Empathy means both people must hold the other's experience as real and valid, even when it is painful to witness.

This model is demanding. It asks the person who broke trust to tolerate sustained discomfort without becoming defensive, which is one of the hardest things a human being can do. And it asks the person whose trust was broken to remain open to repair while still honouring their own pain and boundaries. Neither role is easy. But the model works because it addresses what trust actually requires: not a single act of forgiveness, but a sustained pattern of attuned, reliable, honest engagement.

The trust audit: assessing where you stand

Before you can rebuild trust, you need an honest assessment of what was damaged and what remains intact. Trust is not monolithic. You may trust someone's intentions but not their reliability. You may trust their love but not their judgment. You may trust them in some domains, with your children, with practical matters, but not in others, with emotional honesty, with fidelity.

A trust audit involves sitting down, alone or together, and answering specific questions. Where do I still trust this person? Where has trust been broken? What would I need to see, consistently, to begin rebuilding in the broken areas? What am I willing to do, and what am I not willing to do, during this process? This is not about creating a scorecard. It is about getting specific, because vague feelings of mistrust are much harder to work with than identified areas of concern.

The audit also helps you distinguish between trust that was broken and trust that was never established. Sometimes a betrayal reveals that the relationship was built on assumptions that were never tested. I assumed you would be faithful. I assumed you would tell me the truth. I assumed we had the same understanding of commitment. If the trust was assumed rather than built, part of the repair work involves building what was never there, which is a different task from restoring what was lost.

The repair conversation framework

• Start with impact, not intent. The betrayed person needs to express what the breach did to them, in their own words, without being corrected or contextualised. The sentence I need you to hear what this did to me is the opening that matters most.
• The betrayer listens without defending. This is the hardest part. The instinct to explain, to provide context, to say that was not what I meant is overwhelming. But explanation in the early stages of repair is experienced as minimisation. The only useful response in this phase is I hear you. That makes sense. I am sorry.
• Name what happened honestly. Vague apologies, I am sorry you were hurt, obscure accountability. Repair requires specificity: I lied about where I was. I broke the commitment I made. I chose something else over our agreement. Naming the action without euphemism is painful but necessary.
• Identify what will be different. Not as a grand promise, but as specific, observable changes. I will tell you where I am going without being asked. I will follow through on what I say within the timeframe I give. I will come to you first when something is difficult rather than hiding it.
• Accept that repair is not linear. There will be good weeks and terrible weeks. Triggers will appear months after you thought the worst was over. The betrayed person's hypervigilance is not a failure to forgive. It is their nervous system doing its job. Repair is complete not when the pain disappears but when the pain no longer controls the relationship.

When repair is not the right path

Not all broken trust should be rebuilt. If the betrayal involved sustained deception, abuse, or a pattern of harm that the person shows no genuine willingness to change, repair may not be possible or advisable. Trust repair requires both people to do hard work. If only one person is willing, the process stalls and the person doing the work alone ends up more depleted than before.

Some questions to sit with honestly: Is this person taking full responsibility without deflecting or minimising? Are they willing to tolerate my pain without rushing me to forgive? Have they made concrete changes, or are they relying on promises and apologies? Do I feel safer than I did three months ago, or about the same? If the answers consistently point toward stagnation or continued harm, the bravest thing you can do may be to let the relationship go rather than exhaust yourself trying to rebuild something the other person is not meeting you on.

A grounded next step

If you are trying to rebuild trust, the most useful thing you can do this week is get specific. Not how do I trust again, which is too big, but what is one area where trust was broken, and what would one small, observable change look like? Start there. Trust rebuilds the same way it was built in the first place: one small, reliable moment at a time. The question is not whether you can get back to where you were. It is whether you can build something more honest than what was there before.
