Advice!

Me and this guy dated last summer after we broke up we still stayed in touch I had realized that I still liked him the whole time we were apart. A few weeks ago we got back together and I’m starting to think I made a mistake. Nothing is particularly wrong it just doesn’t feel right and he’s a little clingy and pushy. I think that maybe the only reason I liked him is because I couldn’t have him but now that I do I don’t think I like him anymore. I feel like a horrible person for it. Am I wrong for feeling this way?
