SWTE, you might remember that earlier in this thread I put up a link to rape crisis after you described a horrible incident in Gibraltar? Now's the time to call them and arrange counselling, it sounds as though you will be going through some really difficult emotions right now and you need support.
My stepdad was emotionally and physically abusive. I remember how my mother became completely bound up in this normalised world of violence. She lived it day to day and it just became routine, this is what has happened to you. Now you've left the situation you are able to see it for what it is, and I bet you feel stunned that you hadn't seen it earlier. It's not your fault, this is what abusers do. When your little girl told you what happened you protected her and acted on it immediately- sadly a vanishingly rare response in these situations, you were very brave.
If you are afraid of reprisals from your ex there are a number of precautions you can take, I suggest you call women's aid to discuss them and alert the police to your concerns. I believe that if you pre-warn them they can flag up any calls from your number to receive a quick response.
I'm sure it must feel pretty dark where you are right now, this is when you need your loving friends and family to rally around, please contact them for emotional support.
Keep posting here for support too, if it helps you. There are lots of women here who have been in similar situations and lots of us here who are rooting for you.
When it all gets too much try to remember that there will be a time when all this is a distant memory and you will feel safe.

p.s. I think doing martial arts or some kind of self-defence course is a great idea.
