Coparenting after restraining order..

No we haven't been threw a divorce this occurred 2 months before we were supposed to marry. I just don't know where else to look for advice.

So a year ago my ex was beating on me in front of our 4 year old daughter as he was choking me my daughter threw and hit him with a toy he got off of me and picked her up and squeezed her around her abdomen I immediately grabbed her ran outside and yelled for help. The cops came and he was charged with domestic violence. Cps was involved and has since left. Our restraining order is up in October and I'm trying to figure out ways to co parent. He was not involved what so ever with the cps case he made himself known he was not dealing with them. Now my question is how do I go about letting him see her again. I want to be assured of her safety and he didn't comply with cps so he didn't get the anger management help he needed. I was thinking of starting with him seeing her supervised with his sister in law who I trust, and telling him if he wants more start his anger management classes on his own and take me to court. I'm so nervous for this to be the end of the peace and quiet but I know I can't keep her away from her dad forever.

Any advice will be greatly appreciated because as her mom she is my number one concern.
