I appreciate your reply, but I just have to correct you on one thing. I'm pretty sure she told him she has mental problems (he would have worded it differently if he was guessing she did), so maybe she is using it as an excuse for her behavior. Also, he is not taking advantage of a girl who doesn't realize what she is doing. She told him that she wanted to be drunk the next time they got together because it was her way of feeling less guilty. They both know they are doing something wrong and neither of them care, but it is not entirely on my best friend's side.

I have trouble with the idea of just kicking this kid to the curb. We are best friends, we've always gotten along great. He's really only gone down hill since I left the state (he lives in MA, I moved to WI about 8-9 months ago). He would always tell me things like I was the best thing that happened to him. We've been extremely close for almost three years. I just want him to go back to the guy I met all that time ago...

Thanks again for your reply; I really appreciate you taking the time to read and respond.
