Trust Issues: Where They Come From and How They Change
Kelowna counsellor Lindsey McDonald on why your vigilance made sense once, what the research does and doesn’t support, and how trust actually gets rebuilt.

Someone told you that you have trust issues. Possibly a partner, possibly during an argument, possibly as the line that ended it.
It is a strange thing to be handed. You cannot do much with it, you cannot really disagree with it, and it tends to settle in as a fact about your character rather than a description of something that happened to you.
So here is a more useful version. Your caution came from somewhere. It was almost certainly correct at the time. The question worth asking is not whether you are too careful, but whether your caution is still collecting new information or whether it stopped updating some years ago.
What are trust issues, really?
Trust issues describe a threat-detection system that was calibrated by real evidence and keeps running on that calibration in situations where the evidence has changed. Your system learned that closeness comes with a cost, and it is doing exactly what it was built to do. The trouble is that it stopped taking new readings.
This is a description of a pattern, not a diagnosis. You will not find trust issues in the DSM. What sits underneath, including post-traumatic stress, anxiety and depression, is diagnosable, and the phrase itself is a container people use for a wide range of experiences. That vagueness is part of why it lands so badly when someone says it to you.
Being told you have trust issues also tends to make them worse. The accusation puts you in the position of proving you are not suspicious, which requires you to stop mentioning the things you notice, which means you keep noticing them privately with nowhere to put them. I see the results of that loop fairly often, usually about a year in.
There is a real difference between a person who is careful and a person whose care has gone offline. Careful looks like adjusting: you learn a new thing about someone and your read of them moves. Offline looks like a conclusion that arrived years ago and now processes all new information as confirmation.
What actually causes trust issues?
Trust issues usually come from one of three places: what you watched in the house you grew up in, something a person close to you did to you, and what that betrayal taught you about your own judgment. Most people arrive with some combination of the three, and the third is the one that gets talked about least.
You cannot tell the difference between someone who is safe and someone who is not, so you treat everyone as the second one and hope you are wrong.
Nothing is wrong and you cannot land. Calm registers as the pause before something, so you brace through the good stretch and wait to be proved right.
The less obvious version. Long silence, then everything at once to someone who has not earned it yet, because measured disclosure was never modelled.
The first route is the household. If the adults around you were unpredictable, or warm in public and cold at home, or reliable except during the specific conditions you learned to watch for, you developed a working theory of people early and you have been running it ever since. This is the same machinery I describe in intergenerational trauma, and it shows up most clearly in adult relationships as anxious or avoidant patterns, depending on whether monitoring or withdrawing was the more effective strategy in your particular house.
The second route is betrayal by someone you depended on. Jennifer Freyd’s betrayal trauma theory makes a distinction that matters here: harm done by a stranger and harm done by someone you rely on are not the same injury, because the second one damages the system you would normally use to recover from the first. In a 2014 study of 216 young adults, Robyn Gobin and Freyd found that participants with high-betrayal trauma histories reported clearly lower trust in romantic partners than participants whose trauma had not involved someone close. It is a single undergraduate sample and self-report, so it is a signal rather than a proof, and it matches what walks into the room.
The third route is the one people skip. When a betrayal arrives without warning, you lose more than your trust in that person. You lose your confidence in your own reading, and that loss follows you into every room afterwards. If you missed it once, you cannot rule out missing it again, so you either stop assessing people entirely or you assess them constantly and believe none of your own conclusions. That is closer to a problem of self-confidence than a problem of other people, and it responds to different work.
What do trust issues look like day to day?
Day to day, trust issues look less like accusation and more like administration: quiet monitoring, private record-keeping, rehearsed conversations, and a level of alertness during ordinary evenings that nobody else in the room can see.
- Looking for evidence you are actively hoping not to find
- Feeling steadier during a fight than during a quiet Sunday
- Testing someone rather than asking them the question directly
- Holding back a detail so it cannot be used against you later
- Reading a slow reply as the beginning of the end
- Rehearsing the breakup, the layoff or the fallout in advance
- Finding it easier to be the reliable one than to rely on anyone
The tell I listen for is relief. When something finally does go wrong, some part of you relaxes, because the waiting is over and you were right all along. If you recognise that feeling, you are not paranoid. You are carrying a prediction that costs a great deal to hold, and confirmation is the only thing that ever puts it down.
This rarely arrives labelled as trust. It usually comes in under other names. People book a session about anxiety that looks like competence, or because they go silent in conflict in a way they cannot explain, which I have written about in stonewalling, or because they cannot work out where their emotional boundaries are supposed to sit. Three or four sessions in, we often find a prediction underneath it that has been running unchallenged since long before the current relationship.
Can you have trust issues and still trust people too quickly?
Yes, and it is far more common than the guarded stereotype suggests. The same Gobin and Freyd study found something the headline usually leaves out. Participants with high-betrayal histories said they trusted less, and then, in a behavioural game where they could hand real money to an anonymous partner, they transferred an average of $5.47 against $5.78 for participants with no trauma history. A difference of thirty-one cents.
Reported trust and enacted trust came apart. People who described themselves as unable to trust behaved, in the moment of decision, almost exactly like everyone else.
Freyd’s wider work offers one explanation. Sometimes not knowing is the adaptation. A child who fully registered what a caregiver was doing would have to withdraw from the person keeping them alive, so the mind finds a way to keep depending. Grown up, that capacity does not switch off. You can be highly suspicious in general and completely unguarded with the specific person it would cost you the most to doubt.
In practice this often looks like a swing: months of holding everyone at a polite distance, then telling someone your entire history on a second date because they were warm to you and the dam gave. Both halves are the same problem. It is a calibration problem, and the aim of the work is accuracy rather than more trust or less of it.
Is trust really a chemical?
You will see oxytocin described as the trust hormone, and the evidence behind that phrase is considerably weaker than its popularity suggests. This matters, because the biological version quietly implies that trust is a substance you either have or lack rather than a judgment you make and revise.
The claim traces to a 2005 experiment in which people given oxytocin nasal spray handed over more money in an economic trust game. It was a striking result and it travelled fast, into headlines, into supplements, into workshops. Then, in 2015, Gideon Nave, Colin Camerer and Michael McCullough published a critical review in Perspectives on Psychological Science arguing that the evidence for intranasal oxytocin increasing trust was much thinner than the citation count implied, with small samples and inconsistent replication.
In 2020, a large preregistered replication appeared in Nature Human Behaviour, powered above 95 per cent and including one of the authors of the original 2005 paper. It found no effect of oxytocin on trusting behaviour under conditions comparable to the original. The authors were measured about it, and the finding is clear enough.
I bring this up because clients ask, and because the disappointment is worth sitting with. A hormone you could inhale to feel safe with people is an appealing idea, and it would also mean trust was something applied to you from outside. Trust that has to be built out of evidence is slower and it belongs to you, which is the only reason it is worth anything when it arrives.
How do you rebuild trust after it has been broken?
Trust is rebuilt through a long accumulation of small predictions that turn out to be accurate. He said he would call at six and he called at six. She said where she was going and that is where she was. None of it is dramatic, and the volume is what does the work.
The first thing to name is the asymmetry. The person who broke the trust is usually working to a timeline and wants to know when this ends. The person who was hurt is working from evidence and cannot know in advance how much they will need. Both positions are reasonable. Treating the timeline as the standard is what turns a repair into a second injury.
Apology structure turns out to matter more than apology volume. Roy Lewicki and colleagues tested this across two studies with 755 participants, breaking apologies into six components and measuring which ones moved the needle. Acknowledgment of responsibility ranked highest, an offer of repair came second, and a request for forgiveness ranked last. Which is to say that the two most common moves, explaining why it happened and asking to be forgiven, are the two weakest ones available.
For couples working through infidelity specifically, the Gottman Institute’s approach sequences the work as atonement, then attunement, then attachment, and the order is the useful part. Attempts to restore closeness before the hurt partner’s questions have been answered tend to fail and then get read as proof that the relationship cannot recover.
Two practical notes. Transparency helps and it needs an agreed end point, because open-ended access turns the hurt partner into an investigator and neither person recovers in that arrangement. And the person doing the repairing should expect to bring it up first sometimes. Waiting to be asked leaves all of the work with the person who was hurt.
What helps when there is nobody left to blame?
When the betrayal is years back, or the person is gone, or your partner has done nothing wrong and you still cannot settle, the work moves from the relationship to the prediction itself. A few things reliably help.
Name the prediction, not the distrust. “I have trust issues” gives you nothing to do on a Wednesday. “I expect that if I need something twice, he will start looking for the exit” is specific, and specific predictions can be tested against what actually happens.
Let the body catch up to the evidence. Your conclusions can update years before your chest does. That gap is the main reason people decide the work is not helping, when in fact the slower system is simply slower. I have written about that lag in nervous system regulation, and it is most of what the somatic side of a session is for.
Run small tests with proportionate stakes. Trust is built by risking something you could survive losing, then observing the result. Tell someone a medium-sized true thing. Ask for a small inconvenient favour. The point is a real test with a real answer, rather than a leap that overwhelms your system and teaches it that opening up is dangerous.
Rebuild trust in yourself alongside it. Keep the small promises you make to yourself. Notice the moments your read of a situation turned out to be right, because those are rarely recorded and are the actual evidence base for your own judgment. People who hesitate to trust others usually struggle with limits — both whether to hold them and how to name them clearly — and often find that having specific language ready makes the difference between holding a limit and abandoning it mid-conversation.
Expect it to be uneven. Progress here is rarely a line. A good month, then one ambiguous text and you are back to reading old messages. What changes first is recovery time. The spike still arrives, and it stops taking three days to come down, and eventually it stops running the evening.
When is counselling worth considering for trust issues?
Counselling is worth considering when the vigilance costs more than it protects: when it survives a partner who has done nothing wrong, when a betrayal is months behind you and your body has not landed, or when you can see the pattern clearly and it keeps running anyway.
A few more specific signals. The same ending keeps arriving in relationships that started differently. You are managing a level of private surveillance you would not want described out loud. Or you have decided that keeping people at arm’s length is simply your personality now, which is often what a long-running adaptation sounds like from inside.
There is an honest thing to say about counselling and trust. Peter Fonagy and colleagues describe epistemic trust, our willingness to take in what another person tells us as relevant and worth keeping, and they note that early adversity produces a kind of hypervigilance about who is worth learning from. Which means the people most likely to benefit from counselling are the people least equipped to relax into it. You do not have to arrive trusting me. Saying that out loud in the first session tends to be more useful than performing a comfort you do not feel.
In my practice this work is slow and led by you. I have training in Somatic Experiencing, so sessions often include noticing what your body does while we talk, which matters here because trust is decided in a faster system than the one that produces opinions. You do not need to recount the whole betrayal in detail, and plenty of useful work happens without it.
I offer in-person sessions in Kelowna and West Kelowna, and virtual counselling to anyone living in British Columbia. If you are looking for lower-cost general support first, HereToHelp BC’s module on social support is a reasonable place to start.
Frequently Asked Questions
What are trust issues?
Trust issues describe a threat-detection system that was calibrated by real evidence and keeps running on that calibration in situations where the evidence has changed. The vigilance is usually accurate about the past and inaccurate about the present. It is a description of a pattern rather than a clinical diagnosis, and it does not appear in the DSM.
What are the signs of trust issues?
Common signs include checking a partner for evidence you hope not to find, feeling more settled during conflict than during calm, testing people instead of asking them directly, withholding information so it cannot be used later, assuming a delayed reply means something has gone wrong, and struggling to accept care without waiting for the invoice. One of these alone means little. Several together, in a relationship where nothing has actually happened, is worth a closer look.
What causes trust issues?
Usually one of three things, often more than one at once: what you watched in the house you grew up in, something a person close to you did to you, and what that betrayal taught you about your own judgment. The third route gets the least attention and causes the most trouble, because distrusting your own reading of a situation makes every subsequent situation harder to read.
Can you have trust issues and still trust people too quickly?
Yes, and it is more common than the stereotype suggests. In Gobin and Freyd’s 2014 study, participants with high-betrayal trauma histories reported clearly lower trust yet transferred almost exactly the same amount of money as everyone else in a behavioural trust game. Alternating between total closure and telling a near-stranger everything is a calibration problem rather than a contradiction.
Is oxytocin really the trust hormone?
The claim has not held up well. A 2005 study found that people given oxytocin nasal spray behaved more trustingly in an economic game, and the finding travelled a long way into wellness marketing. A 2015 critical review raised serious methodological problems, and a large preregistered replication published in Nature Human Behaviour in 2020, which included one of the original authors, found no effect on trusting behaviour.
How long does it take to rebuild trust after being cheated on?
Longer than the person who broke it wants and less time than it feels like from inside. Trust rebuilds through many small predictions that turn out to be accurate, not through one long conversation, so the timeline depends on how much ordinary evidence has accumulated rather than on how many months have passed. Most people notice the checking becoming less frequent well before it stops.
How can I trust a therapist if I have trust issues?
You do not have to arrive trusting me. People who have learned to be careful about who they take information from tend to stay careful in a counselling room, which makes sense and is not a reason to stay away. Naming it out loud in the first session usually helps more than trying to override it, and it gives us something real to work with rather than a performance of comfort.
Do you offer counselling for this outside Kelowna?
Yes. I see clients in person in Kelowna and West Kelowna, and I offer virtual sessions to anyone living in British Columbia. A free 15-minute consultation is a low-pressure way to find out whether we would work well together.
Whatever taught you to watch closely was probably teaching you something accurate at the time. The lesson outlived the conditions, and that is a different problem from being broken, and a more workable one.
If you’re ready to take the next step, I’d love to hear from you. Book a free 15-minute consultation.
