Guys help, do you think about your exes? Anyone help?

He 's a real emotional and shaky kind of a guy i think...he just wants to be with some girl and when he feels alone he calls you up...teh way he behaves to you when a new girl comes into his life gives a clear picture of what he is and it would be better you leave him right away and move on. You dont want to be treated like a trash right..I am sure you would feel better once you stop talking to him completely.
