Should I dump my boyfriend?

Well, it sounds to me like he's using you. If you are not happy with your relationship and how your bf treats you, I think you know it's not going to work out in the long run. You sound like you are mature and are trying to get a good start in life by going to college. Find someone who makes you smile and doesn't make you doubt yourself. He sounds like he just wants to have fun and doesn't think about your feelings and doesn't care very much. You deserve someone who is so much better! I say, "Dump him!"
