Is this the right thing..what should i do?

i found out my ex whos the father of my baby girl has been calling me a slut, tramp,dumb and ***** behind my back to his girlfriend. He also tells me to shut up and calls me a dumb when I talk to him. He has also made very vulgur comments to me such as `I couldn`t keep my legs closed` and says he doesn`t have to care about me. I told him he can`t see her because i was so angry and hurt. should i let him see her? or should i not until he respects me.
