I don't want to seem like an assh*le here, but I *might* relate to the guy. If things between you are anything like they were with me and my ex-fiance then perhaps the situation is something like this.

My ex had bad bi-polar and was very emotional. I had (and still have) problems of my own. However I was expected to be the carer of the relationship, while she was the bread-winner thanks to the crazy amount of money she had coming in from benefits. Even though she didn't really do anything for this money, she still saw me as "owing" her for it by providing the attention she needed. After years of this, dealing with her mood swings, her hostility and her selfishness, I just stopped caring about placating her much. I didn't love her any less, but I was out of patience and felt neglected. When she would start scapegoating me, I'd intellectually bully her back. It got fairly abusive towards the end. After we hit a bad spot in life, she sought an escape by throwing herself at the first guy that showed an interest and we parted ways.

But that wasn't the end I would have wanted and it could have been avoided. Like I said, I don't know if your situation is much like my own and I'm probably projecting a bit, but if it is:

Give the guy a break, he's probably tired of dealing with you. If he doesn't have a job, doesn't know what he wants from life, and his family are been less than supportive, he's probably got issues of his own. Being the one who earns might not mean that much in his eyes. He might want YOUR emotional support for a while. Try to reign back your needs, even if it's hard, and look out for him for a while. He might not appreciate it, and it might seem unfair, but the pressure of looking out for you might give him the breathing room he needs to make himself happy. I mean, it might work, or it might just shift the balance entirely into his favor and just make things more broken. If it does, then I'd say that's the time to break up with him. But now? I don't know, feels wrong to me. Like the guys all used up so you're going to take the money and run.
