I belong to a number of mental health forums. My general thought is that if someone refuses to help themselves, why should you sacrifice yourself and stick by them? I urge you to try and talk to him about these issues one more time. Give it your all, and lay it all out on the table. If he doesn't respond in a positive manor, ie agreeing to take care of himself from here on out, then I'd advise you to take steps toward separating your life from his. I think its important to stick by someone's side, but if the other party isn't willing to put in any effort, then it is indeed over. It takes two people making an effort in order to make a relationship work, and even then it isn't easy. If one party has already checked out, then the relationship is likely doomed. I urge you to seek employment so that you have a way of supporting yourself. I know this isn't easy. I wish you the best.
