It’s exhausting. One minute you’re planning a weekend getaway, and the next, they’re packing a bag or sending that dreaded "I can't do this anymore" text. Then, three days later, they’re back. They apologize, you forgive them because you love them, and the cycle resets. This isn't just a "rough patch." When you look at someone who constantly breaks up with you psychology, you’re usually looking at a complex cocktail of attachment issues, emotional dysregulation, and a desperate need for control.
Most people think it’s just about "commitment issues." It’s actually deeper than that.
It's about how their brain handles intimacy. For some, getting too close feels like suffocating. For others, a tiny disagreement feels like a total rejection, so they dump you first to protect their own ego. It's a preemptive strike. They’re essentially firing you before you can quit.
The Push-Pull of Attachment Theory
We have to talk about attachment styles if we’re going to make sense of this mess. Most of the time, the "chronic breaker-upper" falls into the Avoidant or Anxious-Avoidant (Disorganized) categories. Dr. Amir Levine and Rachel Heller, authors of the book Attached, describe these dynamics perfectly.
Avoidants value independence to a fault. When they feel "engulfed" by your needs or even just the routine of a healthy relationship, their internal alarm bells go off. They need distance to feel safe again. Breaking up is the ultimate distance. It’s a giant "Reset" button.
Then there’s the "Fearful-Avoidant" type. These folks desperately want love but are terrified of it. They’ll pull you close until the intimacy feels "too real," then they’ll panic and blow the whole thing up.
- They might cite "incompatibility" over something small like a dirty dish.
- They might suddenly claim they "need to find themselves."
- Maybe they just go cold and ghost for a week before officially ending it.
The irony? Once the breakup happens, the pressure is gone. They start missing you. They remember the good times, the anxiety fades, and they come crawling back. And because you’re likely "Anxious" in your attachment style—meaning you crave closeness and fear abandonment—you let them in. You’ve just reinforced the behavior.
The High of the Make-up
Honestly, some people are addicted to the drama. I’m not saying they’re doing it on purpose to hurt you, but the brain chemistry involved is wild. When you break up, your stress hormones—specifically cortisol—spike. You feel literal physical pain.

When you get back together? Dopamine. The relief of reconciliation creates a massive neurological high. It’s better than the "normal" baseline of a stable relationship. Over time, the relationship becomes a literal addiction. You’re both chasing the peak of the "make-up" phase, which requires the valley of the "break-up" phase to exist. This is often referred to as an intermittent reinforcement schedule. It’s the same psychological trick that keeps people pulling the lever on slot machines. You don't know when the "win" is coming, so you keep playing.
Emotional Dysregulation and the "All-or-Nothing" Mindset
Sometimes, someone who constantly breaks up with you psychology is rooted in personality traits or disorders like Borderline Personality Disorder (BPD) or high levels of neuroticism.
In these cases, the person struggles with "object constancy." When they are mad at you, they can’t remember that they love you. In that moment of rage or hurt, you are 100% the villain. There is no middle ground.
They aren't thinking, "I'm annoyed by this behavior."
They are thinking, "This person is evil and I must escape."
Once the emotional storm passes, their perception shifts back. Suddenly, you’re the angel again. But the damage to the relationship's foundation is already done. You’re left walking on eggshells, wondering which version of them you’re going to get today.
Power Dynamics and the Control Factor
Let’s be real for a second: breaking up is a power move.
The person who ends the relationship holds all the cards. They decide when it’s over, and by coming back, they decide when it starts again. If someone feels powerless in other areas of their life—maybe their job is failing or they have low self-esteem—controlling the "on/off" switch of a relationship gives them a temporary sense of agency.

It’s a toxic way to test your loyalty. They think: "If I leave and they still want me back, they must really love me." It’s a bottomless pit. No amount of "taking them back" will ever fill that void of insecurity.
The Long-Term Cost to Your Mental Health
You can't live like this forever. You just can't.
When you stay with someone who treats the relationship like a revolving door, your nervous system stays in a state of high alert. This is chronic stress. You might notice you’re more jumpy, your sleep is trashed, or you’ve stopped making long-term plans because you don’t know if your partner will even be there next Tuesday.
It erodes your self-worth. You start believing that you’re "difficult to love" or that this is the best you can get. It isn't.
How to Actually Handle the Cycle
If you're in this right now, you have a few choices. None of them are easy.
1. Set the "One More Time" Boundary
Next time they come back—and they will—you don't just say "it's okay." It’s not okay. You have to state, clearly: "I love you, but I cannot do another breakup. If we end this again, it is permanent. I will not answer the phone. I will not see you. It's over for good."
You have to mean it. If you don't follow through, the boundary is just a suggestion.

2. Require Professional Help
The someone who constantly breaks up with you psychology usually requires therapy to fix. It's rarely something a couple can "talk out" over dinner. They likely need individual therapy to address their attachment trauma, and you might need "couples work" to figure out how to communicate without hitting the eject button. If they refuse to seek help, they are telling you they prefer the cycle over your peace of mind.
3. Analyze Your Own Role
Why are you staying? This is the hard part. Often, we accept the love we think we deserve. If you grew up in a household where love was volatile or conditional, this "push-pull" might feel like home. It's familiar. But familiar isn't the same as healthy.
Moving Toward Stability
Real love is boring sometimes. It’s consistent. It’s knowing that even when you’re screaming at each other about who forgot to pay the electric bill, nobody is leaving.
If you’re dealing with a chronic breaker-upper, you have to realize that you are participating in a dance. If you stop dancing, the music has to change. Stop being the safety net. Stop being the person who is always waiting at the finish line with a glass of water and a hug after they’ve spent a week "finding themselves."
Actionable Steps for the "Next Time":
- Go No-Contact Immediately: If they break up with you, don't beg. Don't text. Don't check their Instagram stories. Give them the full experience of losing you. Often, they do this because they know you'll be there. Remove that certainty.
- Write a "Why I Should Stay Away" List: In the heat of the "missing them" phase, you’ll romanticize the relationship. Keep a list on your phone of every time they hurt you, every time they walked out, and how it felt to be discarded. Read it when you feel weak.
- Focus on Core Values: Does "constantly quitting" align with the version of a partner you want? Probably not. Compare their actions to your values, not their words.
- Get Your Own Support: Talk to a therapist or a trusted friend who isn't afraid to tell you the truth. You need an outside perspective to break the "trauma bond."
At the end of the day, you deserve someone who stays in the room when things get hard. A relationship isn't a trial run that you can opt out of every time there's a minor glitch. If they can't commit to staying, you need to commit to leaving—for real this time.
