I just can't say "I want to break up" & mean it! (Abused)

I'm the girl with the abuse problem you may have read in another message on here today, I know he is not showing any remorse. He said but  I hurt him?  He's pretending and saying he's sorry but gets mad when I'm upset about it. I know what should happen but the love I have for him and the good moments won't let me feel my own worth over losing him. I may sound pathetic but I'm hurting so terribly bad on the inside and out. Prayers please. It's just so hard to leave him. My ex used to do this to me, I'm jus beginning to believe it's me.
