Heart Broken

I want to move on so bad but I don't want to move on by dating someone else. My heart won't let me hurt someone the same way that he hurt me. How can he not love me after all the love I've shown him, after always being there for him. What kind of cold hearted person could just rip another persons heart to shreads? I just want to move on, I want to be able to hear his voice or see his face without crying and missing the time we shared. This isn't suppose to be my life. Im suppose to marry the father of my child not be alone with my beautiful little girl.
