When the Breakup and the New Relationship Arrive at the Same Time
You get the "we need to break up" talk, and evidence of someone new shows up around the same time, sometimes even before the breakup is official. In Korean, this is called hwanseung-ibyeol (환승이별, literally "transfer breakup") — the closest English equivalent is monkey-branching or overlapping relationships: starting a new relationship before fully ending the current one, the way a monkey swings to the next branch before letting go of the last. For the person left behind, this often causes deeper betrayal and confusion than the breakup itself. "How could they see someone else before we'd even broken up?" is a completely natural question, and understanding the psychology behind it can lighten some of the weight of self-blame.
Drawing on relationship psychology research and clinical commentary, three overlapping psychological patterns tend to show up in people who do this.
Pattern 1: Fear of Being Alone and Dependency
One of the most commonly cited drivers is dependency. Some people can't tolerate the loneliness of being alone once a relationship ends, the dread of "no one to call this weekend", so they rush into the next relationship before the last one has been properly processed.
Scenario: As soon as things started feeling distant with her partner, A opened a dating app. Her feelings weren't fully resolved, but she needed the sense of "being connected to someone." A new relationship starting before the breakup was even final may say less about her loyalty and more about how little emotional capacity she had to sit with being alone.
Pattern 2: Using New Attention to Patch a Damaged Self-Image
The second commonly cited pattern is self-esteem repair. Repeated experiences of feeling dismissed or unattractive in a relationship can badly erode self-esteem. In that state, a new person's attention and interest becomes an easy way to refill it. What matters most isn't confidence in the new relationship itself, it's the feeling that "someone wants me again."
Scenario: B had spent a long relationship being repeatedly compared to others and put down. When a coworker showed interest, B's feelings shifted toward that person quickly. It wasn't really about falling in love with someone new, it was closer to needing someone who could repair a self-esteem that had been worn down.
Pattern 3: Avoiding the Grief of the Breakup Head-On
The third pattern is emotional avoidance. When someone moves into a new relationship without fully emotionally closing out the old one, it's less about "ending" the relationship and more about "covering it up." Instead of facing the loss, guilt, or emptiness that comes with a breakup, they rush to fill that space with new feelings.
Scenario: C knew the relationship was falling apart but didn't have the courage to bring up breaking up. Instead, C started finding comfort in conversations with someone else, and as that connection deepened, the old relationship naturally dissolved. In effect, C skipped the process of fully feeling and processing the grief before moving on.
Checklist for the Person Left Behind
- Don't jump straight to "it's because I wasn't enough" — the other person's emotional avoidance may be the real cause
- Don't directly compare yourself to their new relationship — it's likely still standing on unresolved emotions of its own
- Instead of chasing revenge or trying to win them back, give yourself time to actually process your feelings
- Fully feeling the grief after a breakup, rather than avoiding it, tends to lead to a healthier next relationship in the long run
- If the sense of loss keeps disrupting your daily life, reach out to people around you or consider professional support
Multiple relationship psychology sources agree that a "transfer breakup" says less about someone's overall character and more about how unequipped they were to handle loss and endings. For the person left behind, the first step toward healing isn't self-blame, it's giving your own feelings the time and care they need.
