My (soon to be ex) fiance and father of my child lies to me. We are currently in a long distance relationship for about 6 years . He goes days without calling or asking about his daughter. He would rather go out all the time. His family never liked me and now hes starting to constantly say his family was right, im a whore, ugly after i gave birth. He's changed completely. When we speak it is only to argue. Out of anger he told me "say whatever you want. I fucked you all i wanted anyway."

How do I start loving myself enough to never speak to him again? Deep down I wish he would be the person he was before but i know he's not. In person it shows he loves his daughter but when he's not physically with her it feels as if he does not feel any connection with her.
