What bothers me the most and what stuck out to me more than anything was the fact your daughter saw what her dad was doing to you. In your own words she started hitting him so he'd let you go. And now the vicious cycle begins for your innocent child. The most unselfish thing you can do is PLEASE get some help. PLEASE let go of this man and let him get his own help. There's nothing you can do for him, but there's plenty you can do for you and your beautiful children who are also victims in this volitile relationship.
