Christa, my heart goes out to you and I have just prayed for your situation. I, too, lived in an abusive marriage, but only for 2 years; I still have the physical scars from one attack, but God has helped me forgive my ex-husband for all he did to me. I can pray freely for him. Fortunately we had no children together. I agree with another post that exposing your child to these awful images is akin to abuse of her little mind. She cannot make sense of these things, and it's confusing and frightening. God hates divorce but He doesn't call his children to abuse, either. I pray for continued courage and wisdom for you. Teen Challenge has a great reputation; hope it helps.
I also had to examine what it was about ME that drew me into a marriage with a man who had tendencies toward abuse. It may help you to get some counseling for yourself along these lines as well.
God can do miracles. Dont' get in his way by enabling the bad behavior of your husband.
HOpe this isn't too straightforward for you. IT' breaks my heart to think of a child going through this with you; and YOU are God's child. I'm sure His heart is hurting, too.
God bless!
