Sounds like you should be able to get sole custody of your daughter, and get a restraining order against him. Be strong. I know he seems all powerful but document the things he does, get proof. If he is really the way you say you can take effective legal action against him even if he is charming and a good liar. You need to be there for your daughter as well as yourself. If he has caused you pain he is causing her even more. Even if you fail and she is mad at you now, years later she will feel that someone tried to stand up for her and be grateful, it will do a lot to dispel the feeling that she is unlovable, which is something many on this forum struggle with.
You can do this. Contacting a lawyer may be a better step than contacting a therapist for now.
