Have you had a boyfriend who said the right things and told you sweet things, only to break-up with you because of false accusations made about you? This is what happened to me. The person I fell for turned out to be someone different. We broke up because I stood for the right things, and now he acts as if I am not even there. I am over him (romantically speaking) but I just wish he would grow up and act his age concerning our break-up. How do you deal with someone who says they care for you only to dump and ignore you when things didn't go their way? How to deal with rejection?
I suppose this is a 2-for-one since you posted another question similar to this. You've broken up with this fella, so why even bother to analyze his behavior to death? Chalk him up to experience. He's already down the road. Go meet other people or be by yourself. Leave him alone.
