I think that you are fooling yourself about this guy. You tried to be "exclusive" with each other and he bailed on you. It takes two to have a relationship. This guys actions are all about hooking up, not on being with one woman.

If what he does makes you crazy, then stop seeing him. He won't change. Stop being his friend w/benefits or his booty call or whatever. You are being used.

As a college freshman you have many potential boyfriends everywhere. Find someone who treats you well and can keep it in his pants.
