I went through a similar situation with one of my mother's boyfriends. It's a tough place to be in. I know you love your dad, but if he is being that inappropriate towards you it is time to leave. Go anywhere that is safe. I know how tough it is to try to go out on your own. It's really scarey, especailly since it has been a while since you were on your own. Remember that his behavior says more about him that it does you, and it is in NO WAY YOUR FAULT. If he can't control himself maybe he needs therapy. If he is that lonely then he needs to do something about it. I mean there are women out there that are just as lonely. It his responsibility to find someone to vent his sexual frustrations on and that someone is NOT his daughter... if he can't get that then he is the one with the problem not you.
It also sounds like he is insensitive about your abuse history. I wonder if he realizes how triggering his behavior really is?
