This isn't your fault. If you can't work then you can't work. Your husband seems like he is able to work. I really don't know your entire situation, but if he hasn't worked in a while. I would (if me) leave him. I also think that if you left him, your dad would help you out more. I bet your dad hates what he is doing to you. You don't deserve to be treated like that at all. Keep posting so we know how you are doing.
