What would you do if your boyfriend/girlfriend cheated on you?

I have to say I love the comments on here as I've been cheated on numerous times before. I normally gave them a second chance but it has honestly never worked out and ended up with them leaving in the long run. I should stop giving people another chance, but I guess I'm just too caring.

Leave him/her... ._. im not staying with someone who clearly doesn't respect our relationship. Besides if he/she cheats it's because the person it's not interested in you or it's an immature person who thinks it can be with everyone he/she wants...

The way I see it, my significant other got bored of me and no longer sees what she saw in me at the beginning. Thus, I would try to figure out where I went wrong and where I screwed up since she no longer likes me and is unwilling to break up with me for whatever reason. Basically, id start blaming myself heavily and try to figure out what went wrong and why this new guy or girl is better than me xD

Hmmm... I couldn't blame the guy, he wouldn't necessarily know she was cheating, but for her, in the same bed we slept together and cheated on me in... Would be her grave... Just kidding, I'd throw dat Bitch out the window, literally, and then have a beer with the guy she was cheating on me with.

I enjoy vengeance. I'd be sure everyone in her friend circle and immediate family (bar Grandparents, I'm not THAT heartless) knows of what she did. Mind you, I'd do this with proof and make sure that this was before I broke it off. Then I'd break it off, tell her I know, and (if we're living together) give her 14 or 30 days to get out, depending on eviction laws. May seem heartless, but cheaters are in the lowest tier of scum in my eyes.
