Betrayal by a parent, partner or anyone we rely on can leave a lasting mark. This guide explains why, what it can look like and practical ways to begin rebuilding.
Trust sits underneath every close relationship. We count on a parent to keep us safe, on a partner to be honest, and on the people around us to look out for our wellbeing. When that trust is broken by someone we depend on, the hurt can run much deeper than ordinary disappointment. At Homeland Care we support people in their homes across Sydney, and we know that emotional wellbeing is just as important as physical care. This article explains what is often called betrayal trauma and some ways people begin to recover from it.
The term usually describes the long-lasting distress that follows one of two kinds of broken trust:
What makes these situations so painful is dependence. If you need someone for shelter, money, affection or protection, walking away may not feel like a real option. Some people end up tolerating the betrayal, and even expecting more of it, simply to stay safe. Over time that pattern can chip away at self-worth, emotional balance and the capacity to bond with others.
Psychologist Jennifer Freyd introduced the concept of betrayal trauma in 1991. She described a particular kind of trauma arising inside important relationships, where the person who has been betrayed still needs the betrayer for care or protection.
Her theory proposes that harm inside attachment relationships, like the bond between parent and child or between partners, can have long-term effects. Ordinarily, a natural reaction to betrayal is to move away from the person responsible. Dependence makes that difficult.
A young child cannot leave a parent who provides meals, a bed and safety, as well as emotional care. An adult with no independent income or social network may worry that admitting the betrayal, or leaving because of it, would put them at risk. Faced with those consequences, a person may push the experience out of awareness. They might never fully work through what happened, and their memory of it may become blurred, particularly when it occurs in childhood.
Early work on betrayal trauma focused on children let down by caregivers. Researchers later recognised that the same pattern can appear in other close bonds.
Attachment theory helps explain why. The relationships we form as small children act as a template for later ones. Secure early bonds tend to support secure adult relationships, while insecure early bonds are often followed by more unsettled ones.
Bringing a child into the world carries an unwritten promise: the parent will protect and nurture them. Children usually trust their parents completely and expect their needs to come first. A betrayal shatters that expectation.
Adult partnerships work on agreements too, even if they are rarely spelled out. You may not rely on a partner for survival, but you probably rely on them for affection, companionship and emotional backing. In a monogamous relationship, both people usually share a sense of what would count as being unfaithful. Infidelity breaks that shared understanding.
Betrayal can affect both body and mind, and the way it shows up depends on the person and the kind of betrayal. Two people with similar experiences may react quite differently.
Unfaithfulness is the most common form of betrayal between partners, though hidden spending or other financial deception can trigger a similar response. People who discover an affair often describe:
Some adults also develop a kind of selective blindness. Even if a partner is not essential for survival, leaving can feel impossible because of shared children, limited choices or financial dependence. Partners also meet deep needs for belonging. Rather than watching for warning signs, a person may, often without realising it, look past them to protect the relationship and themselves.
Effects can appear soon after the events and carry on into adult life. They may include:
Some children cope by dissociating, mentally disconnecting from reality so that painful memories stay out of reach. When a parent fails to protect a child, the experience can feel so contrary to everything the child expects that blocking it out becomes a way to keep the bond intact. “Forgetting” helps them survive in a home they cannot leave, yet the same strategy can later affect memory and a stable sense of identity.
Healing rarely follows a straight line. A person who decides to stay with a partner after an affair may find that trust returns slowly and that doubts keep resurfacing. Someone who blocked out childhood experiences may find memories returning in adulthood, often sparked by a similar event, and discover that pushing them away no longer works or brings relief.
There is no single right path, but the approaches below are a starting point. A GP can also help by talking through what you are experiencing and, if you wish, referring you to a psychologist or counsellor with trauma experience.
In the early days after a betrayal comes to light, everyday self-care often falls away. Small routines can make a difference to how you get through each day:
For people who receive support at home, a trusted support worker can help keep these routines going during a difficult period.
After infidelity, there is no deadline for deciding whether to separate or try to repair the relationship. Taking time is reasonable. A couples or relationship counsellor can help you weigh up whether rebuilding trust feels achievable.
It may feel safer to avoid thinking about the betrayal, but unaddressed hurt tends to leak into the rest of life. Memories can intrude at unexpected moments, such as during a family meal, while helping a child with homework or on the commute.
Turning towards the experience, painful as it is, opens the door to understanding it. After infidelity, that might mean looking honestly at wider issues in the relationship, such as poor communication or emotional distance, and considering whether they can be worked on. This is not about accepting blame. The decision to be unfaithful belongs to the person who made it.
Shame, humiliation, rage, a wish for revenge, nausea and grief are all common reactions. Trying to bury them can make them harder to manage over time.
Labelling each emotion as it arises, whether that is anger, regret, sadness or loss, can make feelings less overwhelming. As you become more familiar with them, it often becomes easier to find healthy ways of responding.
After trust has been broken, reaching out can feel risky. You may not want to discuss what happened at all. Still, support matters most in hard times. Friends and family do not need every detail to keep you company, share a meal or help take your mind off things.
Tell people what you need, whether that is advice or simply someone to listen. If the betrayal involves a partner, think carefully about how much to share with mutual friends, as gossip can add to the pain. Keeping the details within a small circle of trusted people is often wise.
If you are having thoughts of suicide or do not feel safe, call 000 or contact Lifeline on 13 11 14 immediately. You do not have to work through betrayal on your own.
