Child born out of wedlock

I'm hoping you can shed some light on this matter, nonetheless I have a daughter out of wedlock. Her father is Christian. I withheld visitation because I know I've committed a major sin. I've repented and I'm still doing it, anyway is it permissible for him to see and be an active role in her life? I don't know if there's anything I can do because he took me to childrens court. So she goes to him every Sunday. He feeds her food out of their house and they are pork eaters even though I send her lunch and snacks with. He even gives her food out of other Christian peoples house. I once saw his cousin's husband kissing her on her mouth. Any advice will be appreciated.
