The fact that he prefers to stay with "a crazy biploar girlfriend" than in a home concerns me greatly. Maybe you could try staying at your place at night and leaving him on his own. It sounds mean, but it's not. Caretaking is a brutal job at best. The fact that he's verbally abusing you while you are taking care of him is not good at all.

I know that you love him, but you are not obligated to work yourself to death taking care of him, especially when he has other options but instead chooses you to bend over backwards for him.
