I'm so sorry for the pain you are going through right now. It's an unbelievable story and the courage you have shown is remarkable. I agree, the only way to go is the 180 and stick to it.
It's so hard to imagine your WH doing this to you with someone you took into help. All you can do now is concentrate on yourself and your little girl. Put all your focus on that and also continue to come to HH as their is no better place in this world for advice for people who have been in your shoes. They also truly care about you, will look out for you and always be there for you.
