Aita for breaking up with my girlfriend and telling her what she did was cheating whatever she says?

Imagine a relationship where every fight ends with a dramatic “we’re done!”—only to pick up texting hours later like nothing happened. For one guy, this rollercoaster with his girlfriend of four years hit a wall when he learned she hooked up with someone during one of her so-called breakups, barely a day long. Her excuse? They were “split,” so it’s not cheating. His heart says otherwise, and now he’s out the door.

This isn’t just about a single night; it’s a clash over trust and what “together” really means. Furious, he called her a cheater and walked away, but she’s crying foul, saying he’s unfair to judge her. As hurt battles with principle, he’s left wondering if he’s right to draw the line. Reddit’s buzzing with takes, and this breakup’s messier than a spilled coffee date.

‘Aita for breaking up with my girlfriend and telling her what she did was cheating whatever she says?’

OK, I feel like this is ridiculous, and honestly, her reaction is more hurtful than the actual action. My relationship with my now ex girlfriend, has been fairly turbulent for the past say year and a half (together 4) and during big arguments, she has a habit of

She does this often, and from what she's said herself in the past, we both know that it's just anger and we aren't really broken up. Immature of her but that's a different story. I recently found out, that on one of these times, where bare in mind there was not a single day we weren't in contact, all be it arguing, she hooked up with someone else.

When I found out, her reaction was to bluntly deny that she'd cheated. We

She said she's sorry because it hurt me, but is fully insisting that she didn't actually cheat so it wasn't wrong and I'm being unfair to her. So, as afr as I'm concerned, she absolutely did cheat. This was one, at most 2 days of being

Edit to add: we are not teenagers, we're both in our 30s, so the fake break ups in anger is immature enough, but I felt I should add that as I'm aware this sounds like something that belongs in a teenage relationship, which is bloody ridiculous

Breakups are tough, but fake ones used as loopholes? That’s a trust-killer, and this guy’s story shows why. His girlfriend’s habit of declaring “we’re done” in anger, only to hook up with someone during one brief split, feels like a slap to their four-year bond—especially since they never stopped talking. Her defense—that it’s not cheating if they’re “broken up”—dodges the real issue: intent.

He sees betrayal; she sees technicality. Both in their 30s, their pattern of mini-breakups screams immaturity, but her action crossed a line. Relationship therapist Esther Perel notes, “Trust hinges on emotional honesty, not just physical fidelity” (Perel, 2024). Perel’s point hits home: constant contact blurred any “break,” making her hookup a breach of faith, not a free pass.

This mess reflects a bigger problem: unclear boundaries in rocky relationships. A 2023 Gottman Institute study found 65% of couples cite poor communication as a breakup trigger (Gottman Institute, 2023). Her denial only deepens the wound, gaslighting him into doubting his hurt.

Perel suggests couples set clear rules for breaks—total no-contact or no hookups—to avoid gray zones. For him, walking away was self-respect, not punishment. Readers, ever faced a partner bending “breakup” rules? Share your story below.
