you sound like a total asshole, just saying.

there's no question that the dude is a creep and a major asshole and got what was coming, but i think you need to think of things from your cousin's angle. abuse works in very fucked up ways. blaming her for making decisions that were fueled by that abuse and decrying her for being a stupid bitch isn't helping anyone and just adding to her likely thought process that the whole world is against her and her creep of a "boyfriend."
