Loss of trust after betrayal: when what you relied on collapses

“It isn’t really the money that hurts. It’s that I believed him.”

This sentence could be spoken by someone whose business partner left them with debts after fifteen years of working together. It could be spoken by a wife who found messages on her partner’s phone. It could be spoken by someone who discovered that their best friend had been talking about them behind their back for years, or by a sister who realised after her father’s death that her brother had secretly signed the house over to himself. The circumstances are very different. The feeling is surprisingly similar: the ground you were standing on didn’t just shake — it turned out it had never been where you thought it was.

This post is about the loss of trust after betrayal. Not about whether the relationship can be rebuilt — I wrote about that separately in After infidelity: can the relationship be rebuilt — but about what happens inside a person when trust collapses. Everything they lose, why it hurts so much, and why this pain is so often underrated, even when the relationship isn’t a romantic one.

Betrayal has many faces

When we say betrayal, most people think of infidelity. But a breach of trust can happen in any relationship we have invested ourselves in. A friend who gives away a secret. A business partner who hides the accounts. A parent who lied for years about who the child’s father was. A brother who looks after himself when it comes to the inheritance. A colleague who takes credit for your work. An institution you trust that lets you down at the very moment you need it most.

What all these experiences have in common is that you are hurt by someone you relied on. Not a stranger from whom you expected nothing, but a person who was given a place in your life precisely because you trusted them. That is why the loss is double: you lose what was taken from you — money, faithfulness, a secret — and you lose the person you thought you knew.

Friendships and family relationships have a particular difficulty here: we have no rituals for their ending. There is more on how it hurts when a friendship ends without explanation or goodbye in When a friendship ends: a loss without a ritual.

Betrayal trauma: what Jennifer Freyd described

In the 1990s the psychologist Jennifer Freyd of the University of Oregon proposed the concept of betrayal trauma. Her starting point was simple but important: we can’t understand traumatic events only by how much fear and physical danger they bring. There is a second dimension — how much betrayal they contain. In other words, whether you were hurt by someone you depend on and trust.

Freyd showed that this second dimension is linked to particular consequences. Where there is a great deal of betrayal, people more often report being cut off from their own feelings, difficulties remembering the event, and long-lasting problems in relationships. Fear prepares us to fight or flee. Betrayal, though, puts us in front of an impossible choice: if I see clearly what this person is doing to me, I may lose a relationship I need.

Betrayal by a partner, a friend or a business partner usually brings no physical danger. That is why the people around you — and often you yourself — quickly dismiss it with “well, nobody died”. But in Freyd’s model it is an experience that touches precisely the dimension most closely tied to trust and relationships.

What collapses isn’t only the relationship

In 1992 the social psychologist Ronnie Janoff-Bulman described how each of us lives on the basis of three fundamental assumptions we are usually not even aware of: that the world is basically good, that it has meaning and order, and that we ourselves are worthy. These assumptions are like the foundations of a house — as long as they stand, we don’t think about them. Painful experiences can bring them down, and then we suffer not only because of the event, but because we no longer know how the world works.

Betrayal touches all three. “People can’t be trusted” shakes the first. “I did everything right and it still happened” shakes the second. “Apparently I wasn’t worth honesty” shakes the third. That is why, after a betrayal, people often talk not only about the person who hurt them but about everything: that they no longer believe anyone, that they don’t know who they could still open up to, and that they feel stupid.

The relationship researchers John Rempel, John Holmes and Mark Zanna divided trust into three components: predictability (I know how this person will respond), dependability (I can count on them when it matters) and faith (I believe in the relationship even where I have no proof). Betrayal doesn’t usually damage all three equally — more on that further on. You will find a short explanation of the term in the knowledge base under trust.

Why you didn’t see it

One of the most tormenting questions after a betrayal is: “How did I not notice?” People are often more ashamed of this than of the betrayal itself. Looking back, the signs seem obvious — the late evenings, the excuses, the strange figures in the reports, the friend’s coolness.

Jennifer Freyd used the term betrayal blindness for this. When we depend on someone — emotionally, financially, socially — our mind has a good reason not to see the signs of betrayal. If it saw them, it would have to do something, and that would threaten a relationship we need. This isn’t stupidity. It is a protective mechanism that works in favour of attachment, not in favour of the truth.

This insight often brings people relief. Your “blindness” isn’t proof that you are naive. It is proof that the relationship mattered to you. Trust that hasn’t been abused doesn’t look like naivety — it looks like ordinary life. Only betrayal repaints it, in hindsight, as something you ought to be ashamed of.

When the past takes on a new meaning

One of the particular features of losing trust is that it affects not only the present and the future, but also the past. Memories that were happy are suddenly no longer reliable. Was that holiday really happy, or was he already lying then? Was your friend really there for you during your divorce, or was she just collecting stories? People often describe going over old events in their mind again and again, searching for where the lie was.

This circling of thoughts has a name — rumination — and in the first weeks it is understandable: the mind is trying to put together a new, more accurate story. The problem arises when the circling doesn’t stop and spreads from the past to everyone around you. Then it is often joined by hypervigilance: a constant lookout for signs that someone is about to deceive you again. You check phones, read between the lines, look for a hidden motive in every kindness.

In the body, betrayal often shows up as sleeplessness, tightness in the chest, loss of appetite or sudden waves of nausea when you remember a detail. These are the nervous system’s responses to a loss of safety. Mostly they settle with time. If they don’t, or if thoughts appear that you can’t go on living, turn to a doctor and don’t wait: in Slovenia, the mental distress helpline Klic v duševni stiski is available on 01 520 99 00 (every day from 7 pm to 7 am), the Samaritans helpline on 116 123 (24 hours), and in an emergency call 112.

A loss without a name

What is lost in a betrayal? First, the person — even if they physically remain in your life, you no longer see them as you did. Then the shared past, which can no longer be read without doubt. Then the future you had planned: the company the two of you would take forward, an old age with a friend you would go walking in the mountains with. And finally, part of yourself: the version of you that trusted easily.

The people around us rarely recognise these losses as losses. Whoever loses a business partner is advised to see a lawyer. Whoever loses a friend is advised to find new friends. Such losses belong to the group I wrote about in The grief nobody acknowledges: miscarriage, divorce, losing a job. Because nobody acknowledges them, they often aren’t grieved either — they remain as resentment, mistrust or a quiet weariness.

When betrayal leads to the end of a romantic relationship, the loss of trust is interwoven with the loss of the relationship; I wrote about why a break-up hurts much like the death of someone close in Divorce as grief: why the end of a relationship hurts like losing someone you love. Here, though, I am mainly interested in what remains even once the relationship is over: the question of whether it will ever be possible to trust anyone again.

When the people around you hurry

The people around you often have good intentions and a poor sense of timing. After a betrayal, sentences that are meant to help but don’t quickly appear. This is how a conversation between two friends might sound a few weeks after one of them found out his business partner had been systematically stealing from him (composite, not a real person):

“Come on, forget him. He doesn’t deserve you still thinking about him.”
“I’m not thinking about him. I’m thinking about me. For fifteen years I signed everything he put in front of me.”
“It’s not your fault.”
“I know it isn’t. But I don’t know any more whether I can believe you either. And that’s the worst of it.”

That last sentence is the core of losing trust. It isn’t just one person you no longer believe. The doubt spills over onto everyone — including people who have done nothing to you. And it is a loss that is hard to explain, because it is shameful: who wants to admit to a friend that they don’t know whether they can believe him?

If you are the friend, the most you can do is not hurry. Don’t demand that the person “get over it”. Don’t take it personally if they are cautious with you too for a while. Returning trust doesn’t come back through words, but through experiences that accumulate.

Do you have to forgive?

Soon after a betrayal the question of forgiveness also comes up — often not from an inner need, but from pressure from others. “Forgive, for your own sake.” Forgiveness can be freeing, but it isn’t a duty, and it isn’t a condition for healing. Above all, it isn’t the same as reconciliation, forgetting or going back into the relationship. There is a short explanation of this in the knowledge base under forgiveness.

Forgiving too quickly is often just another name for avoiding anger. People who grew up in families where anger wasn’t allowed often decide to “forgive” before they have allowed themselves to feel what happened. Then they wonder why the pain keeps coming back. In relational family therapy, in which I am training, it matters that everything that happened gets space first — the anger, the sadness, the shame — and only then comes the question of what to do with it.

If you do decide to forgive, let it be your decision, not an obligation to others. I wrote about how forgiveness differs from excusing, and why it is sometimes hardest to forgive yourself, in How to apologise and how to forgive — yourself included.

Exercise: a map of trust

After a betrayal, mistrust tends to spill over onto everyone. This exercise is meant to help you sort it again — to separate the person who hurt you from the people who didn’t. It takes twenty minutes and a sheet of paper.

1. Write your name in the middle of the page. Arrange the people you are in contact with around it — those who matter more to you closer in.
2. Next to each name, write down what you can rely on them for. Not in general, but concretely: “always replies to a message”, “doesn’t pass things on”, “shows up when things are hard”.
3. Next to the same name, write down what you wouldn’t trust them with. This isn’t an accusation. We trust most people with some things, not everything — and that is healthy.
4. Look at where the person who betrayed you stood. Were they trusted with more than they had ever shown they could handle? These questions aren’t about guilt, but about understanding.
5. Choose one person and one small thing you will trust them with this week. Notice what happens. Trust doesn’t come back all at once — it returns bit by bit, through experiences that prove themselves.

The exercise won’t erase the pain. But it can help keep one person’s betrayal from becoming a verdict on everyone.

Where this view falls short

Not every disappointment is a betrayal. People change, forget, have their own limits. A friend who doesn’t get in touch as often because they have a small child hasn’t betrayed you. Betrayal is a deliberate breach of trust you could rightly expect. If we read every disappointment as betrayal, we end up alone.

Sometimes part of it is yours. That doesn’t mean you deserved the betrayal — nobody does. But it does mean it is sometimes worth looking at why similar relationships keep repeating. Perhaps you keep trusting people you like too much at the start, or you ignore warnings because you learned at home that it was better not to see. That isn’t guilt. It is information you can work with.

When it involves violence or a crime. When betrayal is connected with violence, threats or fraud, you first need protection, and only then processing. In Slovenia, the SOS helpline for women and children who are victims of violence is available on 080 11 55, and the police on 113. It makes sense to report financial fraud and to consult a lawyer — emotional processing and legal protection don’t exclude each other.

When mistrust lasts too long. If after several months you still can’t sleep, avoid people, relive scenes or can’t work, it is no longer just grief. Then it makes sense to seek professional help — a doctor, a psychiatrist or a psychotherapist. Betrayal sometimes lands on top of older wounds and opens more than was visible at first.

What to remember

• The loss of trust after betrayal is a real loss — of a person, of a shared past, of a planned future and of part of yourself.
• Betrayal doesn’t happen only between partners: you can be betrayed by a friend, a business partner, a relative or an institution.
• Jennifer Freyd showed that betrayal is a distinct dimension of trauma, separate from fear.
• Not having seen the signs isn’t naivety but betrayal blindness, which protects a relationship you depend on.
• Forgiveness isn’t a duty; trust returns slowly, through new experiences — and often more considered than before.
