It's perfectly normal that you still think about him. One, he was your bf. Two, he assaulted you.
The trauma from the assault is still there, and of course since it was him, you will be thinking about him. But, since you just broke up, you're most likely very sensitive right now, so whilst most people are able to have a "clean" break, you can't.
I guess you just have to try and bear it until some kind of judgment is reached, then you will finally be able to get on with your life. Do not kid yourself that anything you are feeling for him right now is love, you are very confused, and of course you should be. Try to spend as mcuh time as possible with your good friends and your family, and do NOt under any circumstances make contact with that person.
I wish you all the best hun. x
