What the ****? How bout you give us details as to WHY it is that you want to break up. Because you abuse multiple harmful and illegal substances? Because you smoke and she tries to help you by getting you to quit? Is it because you once cheated on her, and it was somehow oh so within your right? Is it because you call her a cunt, and are perfectly willing to make her feel worse than she has to about YOU ending a relationship with her?
WHAT IS WRONG WITH YOU?
