Like Alice suggested, I know that it often takes that big push to get me moving sometimes too. I remember one time my phone rang, somehow my son's cell had been nudged to redial or something to make it connect to mine, unknown to him. I heard him making his "deal" and getting his drugs and I remember wanting to hang up so bad but was just frozen in fear listening. I think God needed me to hear that. They say coincidence is God's way of remaining anonymous, and there is no doubt in my mind that the phone call was no coincidence.
That was one of the times when I was able to face head on exactly what I was dealing with and I knew that I could not live like that anymore.
Not only is he an addict, he is violent and out of control and your safety and the safety of your baby may depend on keeping a distance between you, even while you decide what you want to do next. Addiction escalates, domestic violence escalates, next time you may not be so lucky as to get away alive.
My prayers go out for you and your baby.
Hugs
