Ex boyfriend issues

Okay so I had a boyfriend that I was really serious about and the main problem was that I was moving to Texas with my parents and we were together from march 2012 to sept 2012 and he didnt care he still wanted to be with me. So the day I was leaving we left off of good terms and then he was acting weird when we were texting then we just stop talking and the week after I get a text from a good friend from high school saying that she and him kissed and hanged out a couple of times and it was just one week after I left all this happen. So I recently visited my hometown and I was staying at my best friend's house and so he's around because I met him from her and he wants to be cool and I feel he doesnt deserve it because I didn't even get a sincere sorry. So now I'm stuck I don't know what to do because I'm moving back to my hometown and he's going to be around

Move on and ignore him. Find someone honest like yourself!
