Please, please help me what should I do!? break up, or make up?

Nooo, if he calls his ex-girlfriend a skank, one day, he'll be calling you that, too. He obviously doesn't care about feelings and that whole letter looked like he was just trying to sound dramatic. And not taking charge for what HE DID or even saying something like, " I screwed up because we were apart..." shows that he shirks his responsibilities, especially when he said he did it because "it's what I do." That's the biggest player excuse I've ever heard, right before, "boys will be boys." Sorry, Rachel, but I do think that this guy will ruin your life, if not already. Please at least think about what I've said. Okay? Okay. Thanks and good luck! :)))
