I'm not saying that you should give up on him persay. But if he loves you as he should, then he should recognize that he has a problem (IE, depression or whatever it is), and do something to fix it. If he was working on his problems, I would agree with you 100% that you should stick through it and do all in your power that is fair to make it work. But based on what you have said, it sounds like he isn't doing that.
