Man, I hate cheatersss. If you're not happy with the relationship, then leave.

Right, it's really something I can't understand... unless you're in an abusive relationship or in one you can't "escape" from (like arranged marriages or something like that) how can you just wake up and choose to cheat on your partner instead of leaving, without feeling like the shitty person you are? I couldn't even look at myself in the mirror, it would be much worse than breaking up. I mean, if you don't have the courage to break up, how do you even have the face to cheat?

Exactly. The guilt and shame would eat me alive.
