Actually the cheating and rationalizations are not the most triggering part for me. It's when she admits she didn't want to be in the relationship anymore, so she turned into a huge bitch to him, so that he would break up with her. Jesus that's pathetic, cruel and a really cowardly thing to do.  After being a cunt to the guy she claims to rly care about, she slowly escalates her degeneracy into fucking someone else and not being careful about who finds out, so that he would eventually find out and break up with her. She then mentions how he finally took charge, like she did him a favor. What a fucking low life.
