Yes, there are so many other good men out there, don't waste anymore of you time with this man. Do whatever you have to do to stop thinking of him like taking a class outside of college, find something new to do like a craft or something, get your mind off of him, to me he seems like a player and that is one thing you don't need is someone who is using you.You mentioned you felt free when he first broke up with you and to me that is one of the best feelings I've ever experienced when breaking up with someone who is being selfish in the relationship. I do know how painful it can be too, it feels like a knife in your heart.
