Where the 'People Always Leave' Belief Comes From
This belief usually begins in childhood when someone important left, died, or withdrew their attention without warning or explanation. Not every departure creates this core belief — it depends on how a child makes sense of what happened. If a parent died and the child was told clearly what happened, they may grieve without internalising a belief about their own abandonment risk. But if a parent left and the child was left to interpret why, or if a caregiver was inconsistently present (there one day, emotionally unavailable the next), the child often concludes: I must have caused this, or I will cause it again, or everyone eventually does.
Aaron Beck's cognitive model explains how this works. Early experiences create schemas — core beliefs that act like templates for interpreting future events. A child whose parent left may form the schema: "I am unlovable" or "People cannot be trusted." These are not conscious decisions. They are conclusions a young nervous system draws to make sense of pain it cannot otherwise explain. From that point forward, the schema runs quietly in the background, filtering how the person perceives relationships.
How the Belief Shows Up in Your Thinking and Choices
Once this belief is in place, it operates through automatic thoughts — the constant low-level commentary your mind produces without your asking for it. When a partner is late coming home, the automatic thought is not "traffic happens." It is "They are losing interest." When someone you trust is quiet, the thought is "I've done something wrong." When a relationship deepens and demands more vulnerability, the thought is "This is when they will see the real me and leave."
These are not paranoid interpretations. They are your nervous system running a prediction algorithm based on old data. The problem is that the data is wrong — it was collected when you were small, in a specific context, with limited information. But because these thoughts feel true (you have lived with them your whole life), you tend not to question them. This is what Albert Ellis and later theorists called cognitive fusion — treating a thought as a fact simply because you are thinking it.
In relationships, this belief drives specific patterns. You may leave first, before they can leave you. You may test people repeatedly — creating small conflicts to see if they will abandon you, which paradoxically exhausts them and sometimes causes the abandonment you feared. You may choose partners who are already somewhat unavailable, because that familiar feeling of uncertainty confirms what you already believe about love. Or you may stay in relationships that harm you, because the known harm feels safer than the risk of being alone.
The Schema Layer Underneath
Schema therapy, developed by Jeffrey Young, identifies what it calls early maladaptive schemas — deeply rooted patterns that persist because they feel familiar and because they seem to protect you. The "people always leave" belief is often linked to schemas like Abandonment, Mistrust, or Defectiveness. These schemas feel true because they have predicted your reality for so long. They have kept you vigilant, scanning for signs of rejection. That hypervigilance feels like evidence that the belief is correct, when actually it is just the belief operating as designed.
The belief also creates what therapists call a self-fulfilling prophecy. Because you expect abandonment, you behave in ways that either push people away or attract people who will eventually leave. Then when they do leave, the belief feels confirmed. You were right all along. The problem is not the belief — it is that you are unlovable. But the problem was actually the belief itself, generating the very outcome it predicted.
What to Notice About Your Own Pattern
The first step is recognising when this belief is active in your thinking. Pay attention to the moments when you assume someone is leaving before they have said so. Notice when you interpret neutral events (a delayed text, a cancelled plan) as evidence of rejection. Notice when you withdraw from someone you care about, telling yourself you are just being realistic about how things always end. These are automatic thoughts arising from the core belief.
The second step is separating the belief from reality. Ask yourself: What evidence do I actually have that this person is leaving? What am I assuming based on my past, not on what is happening now? This is not positive thinking or forcing optimism. It is accurate thinking — looking at the data you have rather than the prediction your schema is making.
The third step, which takes longer, is recognising that you survived the original loss. Whatever happened when you were young, you are still here. The belief kept you safe by preparing you for pain, but that protection came at a cost. It may have prevented you from being hurt by some people who would have left anyway, but it also prevented you from being close to people who would have stayed.
Your values are often in conflict with this belief. You may deeply value connection, loyalty, or intimacy — but the belief that people always leave makes those values hard to live. If you want to understand where your values actually lie and where this belief is blocking them, the beliefs values assessment at My Values will surface both. It ranks what matters most to you and shows you where you are living those values and where you are not. That clarity is where change becomes possible.
Is the 'people always leave' belief the same as abandonment anxiety?
Related but not identical. Abandonment anxiety is the emotional response — the fear and panic. The belief is the thought pattern underneath it, the conclusion your mind draws about why people leave. You can have one without the other, though they often travel together.
Can this belief change if I just understand where it came from?
Understanding is necessary but not sufficient. Knowing that your parent left when you were five explains the belief, but it does not automatically change how your nervous system responds to uncertainty in relationships now. Change requires repeatedly noticing the belief active, questioning it against current evidence, and allowing yourself to experience relationships differently over time.
What if people have actually left me multiple times?
Then you have real evidence, but it is incomplete evidence. Some people do leave. Not all people do. The belief converts some experiences into a universal rule. The work is not denying that people left, but distinguishing between "this person left" and "all people will leave," and examining whether your own behaviour (driven by the belief) has contributed to outcomes.
How long does it take to change this belief?
It depends on how old the belief is, how much evidence you have accumulated for it, and how consistently you work with it. Some people shift it in months with focused effort. Others work on it for years. What matters is noticing it operating and gradually building a different relationship with it, rather than expecting it to disappear overnight.
