It starts with a heavy feeling in your chest when they don't text back for three hours. Maybe you find yourself doing "the scroll"—casually checking their Instagram following list at 2 a.m. to see if any new names popped up. You hate yourself for doing it. You know it’s toxic, but you can’t stop. This is the reality of trust issues in relationship dynamics, and honestly, it’s exhausting for everyone involved.
Trust isn't a light switch. You don't just "have it" or "not have it." It’s more like a bank account where the currency is consistency. When the balance hits zero, everything feels like a threat.
The science behind why your brain won't let you relax
Most people think trust issues come from being cheated on. That’s a big part of it, sure. But researchers like Dr. Amir Levine, author of Attached, point toward something deeper: our attachment styles. If you grew up with "anxious attachment," your brain is basically wired to look for signs of abandonment. It’s an evolutionary survival mechanism. Your amygdala—that tiny almond-shaped part of your brain—screams "Danger!" the moment your partner seems distant. It doesn't matter if they’re just busy at work. To your brain, they are leaving you.
Then there’s the "Betrayal Trauma" theory popularized by Dr. Jennifer Freyd. It suggests that when someone we depend on for survival (or emotional stability) breaks our trust, our brain undergoes a cognitive shift to survive the trauma. We become hyper-vigilant. We look for patterns where there are none. We become detectives in our own living rooms.
It’s not just "in your head"
Sometimes, your gut is actually right. This is where it gets tricky. We live in an era of "gaslighting," a term that gets thrown around too much, but describes a very real phenomenon: when one partner uses psychological manipulation to make the other doubt their own sanity. If you feel like there are trust issues in relationship stages of your life, you have to distinguish between unfounded paranoia and evidence-based suspicion.
If they’ve actually lied about big things—money, talking to an ex, drug use—your "trust issues" are actually just "accurate observations."
How digital life wrecked our ability to feel secure
Let's talk about the phone. It’s the "black box" of modern relationships. Before 2005, if your partner was home, they were home. Now, they can be sitting right next to you on the couch while emotionally engaging with 500 other people.

Technology has created a "low-cost infidelity" environment. Micro-cheating—liking a thirst trap, sending a "flirty but not really" DM, or keeping a Tinder profile "just to see who's out there"—creates a constant state of low-level anxiety. A study published in Computers in Human Behavior found that high levels of Facebook usage were significantly associated with negative relationship outcomes, largely mediated by "Facebook-related conflict." It’s not the app’s fault, but the access it provides makes building trust feel like trying to build a sandcastle during high tide.
Breaking the cycle of "The Investigation"
So, how do you actually fix this? You can't just tell someone to "be more trusting." That’s like telling a person with a broken leg to "just walk better."
1. Radical Transparency (The 100% Rule)
If trust is broken, the person who broke it has to surrender their right to privacy for a while. This is controversial. Some therapists say "don't give up your passwords," but experts like Dr. John Gottman, who has studied couples for over 40 years, suggest that rebuilding trust requires "verifiable transparency." If you’re the one who messed up, you don't get to be offended when your partner asks who you're texting. You've lost the benefit of the doubt. You have to earn it back with months—maybe years—of being an open book.
2. The "State of the Union" Meeting
Gottman recommends a weekly check-in. This isn't a time to fight. It's a time to ask: "What did you need from me this week that you didn't get?" It sounds cheesy. It works because it prevents small resentments from festering into massive trust issues in relationship meltdowns.
3. Check your "Cognitive Distortions"
Are you mind-reading? "They didn't call because they’re bored of me."
Are you catastrophizing? "They’re 10 minutes late, they must be in a ditch or with someone else."
Write down your fearful thought. Then write down the actual evidence for it. Usually, the "Evidence" column is pretty empty.
When to walk away
Honestly? Some trust issues are unfixable. If you’ve been in therapy for a year and you’re still checking their phone every night, the relationship is already dead. You’re just hauling the carcass around.
Trust requires a "leap of faith," but you shouldn't leap if there’s no net. If your partner is defensive, calls you "crazy" for having feelings, or refuses to change their behavior to make you feel safe, you aren't dealing with trust issues. You’re dealing with an untrustworthy partner. There is a massive difference.
Actionable steps for right now
If you’re spiraling tonight, do these three things:
- Put the phone in another room. Physical distance from the device you use to "investigate" reduces the dopamine hit of the search.
- Use "I" statements, not "You" accusations. Instead of "You're always hiding your phone," try "I feel incredibly anxious when I see you turn your screen away, and I need some reassurance." It sounds weak, but it prevents the other person from going into "combat mode."
- Seek "Individual" therapy before "Couples" therapy. You need to figure out if your lack of trust is a "you" problem (childhood trauma) or a "them" problem (they are actually shady) before you sit in a room together.
- Establish a "Grace Period." If a major betrayal happened, agree that for the next 90 days, there are no "dumb questions." The hurt partner gets to ask whatever they want, and the other partner agrees to answer with patience.
Rebuilding a connection after it's been shattered is the hardest work you'll ever do. It requires a level of vulnerability that feels almost dangerous. But a relationship without trust isn't a partnership—it's just a very stressful hobby. Choose to build or choose to leave, but don't choose to stay in the middle.
