If that's the case I guess it's best to just distance yourself from him as much as you can physically and emotionally. Opening up and being shot down hurts more than just keeping it to yourself and finding other ways to get that out (find some other type of support network whether that be a friend, a therapist, or a support group). If it's possible work on getting on the track to financial independence. If it gets bad to the point you feel you HAVE to leave, you can do it. There are DV programs that will help you get on your feet without relying on him.

He obviously doesn't have a genuine connection to you, so I wouldn't act like you do to him.
