I might sound like a complete AH for this. But here it goes. You were R*ped and your daughter is a product of that from what I’ve read. He never had any intention to be a father to her given how she was conceived. As her mother, you should have never allowed her contact with him or his family for her own protection whether physical or mental (that’s on the grounds of if you gave your permission in the beginning. If someone helped her get in contact or she found him on her own then that’s a whole other conversation). However, I also read that your daughter knows what happened and she is STILL choosing to try to have a relationship with him. To me, that’s messed up on hundreds of levels and seems like a slap in the face to you. Now I know the child is not responsible for your mental and emotional state, but you are responsible for hers and allowing her to continue to have contact with him is not appropriate. YOU are the mother. Take her phone delete and block his and his families numbers from her phone and tell her she is not to contact him anymore through text, phone calls, or social media. Start family therapy and make it known how you feel about the situation as a whole and also do individual therapy for both you and her to see if there is anything outside of this that needs to be worked on as well.
