You didn't mention how long you dated, how long you knew each other, etc.  It definitely sounds like some pieces are  missing out of this picture.   when I read some of the other posts and then your follow ups the picture is becoming clearer.  As I understand your post he just wants someone to care for his physical illness.  Your husband sounds very angry, aggressive and he doesn't want to mix love in with you as an employee to fetch and get for him.  I get the definite impression he is abusive with you (psychologically, probably verbally, and physically in the future if not already!)  Does he have any other addiction problems i.e.- alcohol or drugs (either legal or illegal)?  My opinion and i do not have a PhD  in marriage, get the hell out of there, this is not a marriage its an arrangement with no good for you, only himself!!  God bless you and please be careful.  Janie
