What's the number one reason you would break up with someone?

I think that once a woman cheats, it tells me that she is no longer into me or that she is into being with other people as well as or instead of me. At that point, I would want to move on and find someone who was into me and not other people as well.

Ha, I knew everyone is going to pick cheating so I lied and said temper bwahahahha

I would vote for getting bored of the relationship as my main reason. Sometimes I just feel like I'm missing out on the Single-Guy Clubbing Life if I commit to a long-term relationship.

Annoyance is that a reason. How about frustration, how about controlling.

i guess that's a rather relative approach,for I find different reasons for different f***ed ups to break up,

boring or not enough sex

They all suck.

I feel like immature covers a lot of things because when someone cheats or its a one sided relationship that's being immature.

cheating for sure. my boyfriend cheated on me. and he didn't think he did anything wrong. ha asshole.

Choosing between cheating and abusive is tough. I chose cheating because I will hit someone in the head with a cast iron pot for hitting me. Then I'd call the police. It's a done deal after that. I can get my revenge on abuse. But cheating, that just edges it out over abuse.

It's a toss up between cheating and abusive but I chose abusive as the top reason as I have had that end a relationship immediately. And as far as I know I have not had anyone cheat on me.

All of the things you mentioned but make me want to break up with someone but I think abuse (physical or emotional) would make me want to get out immediately. After that the cheating I would not tolerate under any circumstances
