He wants me back after pushing me away for another girl?

My ex pushed me away for another girl and she hurt him so now he’s back telling me he wants to be with me. The only thing is he’s still talking about how she hurt him, which means he’s obviously not over her. He told me he felt nothing for her but I guess he finally told me the truth. I feel like such a joke. The thing is we used to be in love and it was good and now here we are. It breaks my heart.
