let it go

my ex boyfriend and I were dating about 5mths. I really fell for him the first day I met him. He moved in and I got pregnant. Had an abortion because I saw the relationship going in the drain. After the abortion he dumped me. It showed that he wanted to be free and he probraly wouldn't have stuck with me and the kid anyway. I want him back and I been humiliating myself by calling him,texting him, and the result is the same. He still is not intrested in a relationship with me.What I should of done in the beggining was to let it go when I saw it was going to be disaster. The only thing I can do now is to move on and pray that the pain go away because if i don't let it go, I'll be hendering myself of certain things.
