How do I move on from being hurt?

To make a long story short I got left for someone else.He told me he didn't have anymore feelings for her that he was done with her. He said that he never wanted to hurt me and that from now on it was all about us. All of a sudden he started to change and he finally told me he still had feelings for her. I was hurt but I loved him so much I told him if that's who you want to be with I don't want to keep you here and your unhappy. All he could say was I don't know where I want to be but he steadily telling me he loves me and he never meant to hurt me. So Im crying my heart out while we were on the phone and then all he says to me is "IM JUST GOING TO STAY WITH YOU BECAUSE I SEE YOU CANT GET OVER ME" I was so hurt how he could just be so cruel after I put my heart on the line for him. And I never would've done anything to hurt him whenever he made me cry I forgave him, I never got loud with him or cursed at him or left him hanging or anything I just always wanted to make him happy. But even though he said what he said to me and that he wanted to leave me I still said I love you he said it back and hung up we haven't talked since. I know I shouldn't be waiting on his call but sometimes I do its been about 4days now but its hard to make the pain im feeling go away. I just want to know should I feel bad or wrong for anything
