Be VERY careful here. If he has not ever touched them then really you are not talking about abuse, or the kind that a court is likely to do anything about (correct me if I am wrong someone).
I also am a little unsettled that you would now start bringing up accusations like this. I hope you are not just projecting his anger towards you into his relationship with his girls. Sure, he may GET angry at them because of your sitch but for you to say he would actually hurt his own Ds to get to you is a really strong accusation, one that at the moment, considering your feelings overall, honestly rings a LITTLE of revenge.
Emily, I am not saying you are making this up. What I am saying is that I truly hope YOU don't resort to trying to use the girls against HIM much in the same way you are accusing him of potentially using them against you. If he is truly abusive, then the girls need to be protected but if it's simply that you don't like him and he gets angry sometimes so you don't want them around him, I don't THINK that's enough for anyone to do anything.
I hope other's will chime in here because I think this is an important thing to talk about in your case and I may be way off.
