I have been thinking about my ex a lot lately?

It's been almost a year since we ended things. We couldn't even manage to be boyfriend and girlfriend and he definitely showed me what a horrible person he is. I know that it's wrong to still think about him but lately he's in my mind a lot. Also I just learned people in my school are still talking about us. His name keeps popping up out of nowhere. He moved to another city so he doesn't have to deal with anything that I'm dealing with right now so maybe it's just anger but I don't know. I honestly believe I did move on. I like someone else but I can't get him out of my mind, what should I do?
