Hi thank you so much for your replies, I left. stay in friend's place now. I know it is right choice to do to leave him. But things would be easier if he is just an alcoholic not in depression. he is so alone, far away from families and home, I'm the only friend/ girlfriend/family he has, he needs someone to talk to, at least when we are together, he would try not to drink, but when he is alone, he just totally don't care... how can I leave and just watch all that happen?
