You’re sitting across from them at dinner, and suddenly, the air feels heavy. You said something—maybe a joke about a movie or a comment about your day—and their face shifted. Not a big explosion, just a coldness. Now you’re retracing your steps. Did I say something wrong? Why am I apologizing? If you’ve been there, you’ve felt the quiet, buzzing anxiety that defines toxic traits in relationships. It isn’t always a cinematic blow-up with glass shattering against the wall. Often, it’s just a slow, exhausting erosion of who you are.
Honestly, the word "toxic" gets thrown around way too much on TikTok. People use it to describe a partner who forgets to text back or someone who likes a specific type of music they hate. That’s not toxicity; that’s just being a human who is occasionally annoying. Real toxic traits are patterns. They are repetitive, harmful behaviors that create a power imbalance. Dr. Lillian Glass, who actually helped popularize the term in the 90s, describes a toxic relationship as any relationship between people who don’t support each other, where there’s conflict and one seeks to undermine the other. It’s a drain.

The Subtle Art of Gaslighting and Why Your Brain Buys It
Gaslighting is the heavyweight champion of toxic behaviors. It’s named after the 1944 film Gaslight, where a husband tries to convince his wife she’s goind insane by dimming the lights and denying it. In real life, it’s sneakier.
It sounds like, "I never said that, you're imagining things," or "You're too sensitive." Over time, this actually changes your brain chemistry. When someone you love constantly denies your reality, your amygdala—the brain's fear center—goes into overdrive. You stop trusting your own memory. You start checking your phone logs to see if you actually sent that text. You become a detective in your own life, hunting for proof of your own sanity. It's exhausting.
I’ve seen people who are brilliant, high-functioning executives lose their entire sense of self because a partner spent two years telling them they were "unstable" every time they brought up a valid concern. It’s a slow-motion car crash of the psyche.
Emotional Volatility and the "Walking on Eggshells" Tax
Ever feel like you’re managing someone else’s weather?
If your partner’s mood dictates the entire atmosphere of the home, that’s a massive red flag. This is often linked to intermittent reinforcement. In psychology, specifically B.F. Skinner’s work, we know that if you give a reward only sometimes, the subject becomes obsessed with getting it. If your partner is mean 70% of the time but 30% of the time they are the most loving, incredible person on Earth, you will stay. You'll stay for that 30%. You’ll work twice as hard to trigger that "good" version of them.
- The Silent Treatment: This isn't just "taking space." It’s a tool used to punish. True communication requires a "we" approach, but the silent treatment says, "I am withdrawing my love until you perform the way I want."
- Love Bombing: This usually happens at the start. Intense praise. Constant texting. Grand gestures. It feels like a movie, but it’s actually a way to build a foundation of obligation so they can control you later.
- The "Jokes" That Bite: "Don't be so dramatic, I was just kidding." If their humor always comes at the expense of your dignity, it isn't humor. It’s a localized attack disguised as a joke to give them plausible deniability.
Is It "Toxic" or Just a Communication Breakdown?
We need to be careful here.

Not every bad habit is a sign of a toxic person. John Gottman, a famous psychologist who has studied couples for over 40 years, talks about the "Four Horsemen" of a relationship: Criticism, Contempt, Defensiveness, and Stonewalling. Contempt is the biggest predictor of divorce. If your partner looks at you with actual disgust, that’s a deep-seated issue.
But sometimes, people are just bad at talking.
A toxic trait is generally characterized by a lack of empathy and a refusal to change. If you say, "Hey, it hurts when you mock my career," and they say, "I'm so sorry, I didn't realize it landed that way, I'll stop," and they actually try—that’s growth. If they say, "You're just insecure," and do it again the next day? That’s toxic. The difference is the intent and the pivot.
The Financial and Social Straightjacket
Isolation is a classic move.
It starts small. "I don't really like your friend Sarah, she's a bad influence." Then it’s, "Why do you need to visit your parents this weekend? I thought we were spending time together." Suddenly, your world is the size of a postage stamp. You have no one to talk to, which means no one can tell you that your relationship isn't normal.
Financial abuse is another silent killer. Maybe they "manage the money" so you don't have to worry. Or they critique every cent you spend while they buy whatever they want. According to the Allstate Foundation, financial abuse occurs in 99% of domestic violence cases. While not every toxic person is physically violent, the control of resources is a primary way to keep a partner trapped. If you don't have the "exit money," you can't leave the toxicity.

Can You Fix Toxic Traits in Relationships?
Maybe. But usually, no.
That’s a hard truth to swallow. We love a redemption arc. We want to be the "one" who changed them. But toxic behavior is often deeply rooted in personality disorders or childhood trauma that requires professional intervention—not just "being nicer."
If both people are willing to go to individual therapy (not just couples therapy, which can sometimes be dangerous in abusive dynamics), there’s a slim chance. But usually, the "fix" involves the victim changing their boundaries so much that they disappear. You shouldn't have to set yourself on fire to keep someone else warm.
How to Actually Get Out
If you’ve realized you’re dealing with toxic traits in relationships, the worst thing you can do is announce your departure with a big, emotional speech. To a toxic person, that’s just a challenge. They will cry, they will promise the moon, or they will flip the script and make you the villain.
- Document the Reality: Keep a secret journal or a digital note. Write down what happened. "Tuesday: He called me a loser because I forgot the milk. Then he denied saying it." Read this when you feel weak. It anchors you to the truth.
- Rebuild the Village: Reach out to the friends you drifted away from. You don’t have to give them the whole story yet. Just start being "you" again outside the relationship.
- The Grey Rock Method: If you can't leave yet, become as boring as a grey rock. Give short, non-committal answers. Don't share your feelings. Don't argue. Give them nothing to feed on.
- Financial Independence: Even if it’s just $20 a week in a hidden account, start building a safety net.
Leaving is a process, not an event. It takes the average person seven attempts to leave an abusive relationship for good. If you’ve left and gone back, don't beat yourself up. The "trauma bond" is real—it’s a physical addiction to the highs and lows. Your brain is literally craving the dopamine hit that comes after the fight.
Break the cycle by acknowledging that you deserve a boring, stable, supportive love. Love shouldn't feel like a high-stakes poker game where you're losing every hand. It should feel like home. If it feels like a battlefield, it’s time to put down the weapon and walk away.
