Why am I still so in love with my child’s father?

If I’m away from him and I don’t see him I do OK. We have always had a tumultuous relationship where he would never fully commit to me. We ended up having a daughter together. He never wanted to be a family with us. My foolish self never let go of hope. I thought I was moving on until today he dodged a question of if he’s seeing someone. He said it’s none of my business. My heart shattered in pieces. No I can’t stop crying and wondering what’s wrong with me that he didn’t want me. It’s been a year and I still can’t seem to MoveOn. How do I get past this pain?
