What happened to you sounds so much like what's happening with me. He has already calmly broken up with me several times and then comes back and starts treating me nicer for a few weeks. Then he acts distant and cool as though he doesn't need me. I feel like he loves the control he feels over me because he knows how sensitive i am. He's playing a game and I'm not. If he wants me he will have to step up to the plate. It's hard but there's no excuse for him not to treat me better.. and i know I've allowed it to go on. But a warm body sure is better than loneliness. I've become addicted to the sex.. I've never felt like i do with him. But i have to have some composure and control. .otherwise he will continue to behave like an immature teenager that chooses selfishness over companionship and a meaningful relationship.
