What 33girl said. Different things work best for different couples, but for many, it doesn't have to be all or nothing. Plenty of people agree to redefine things and see others while at college.

This distance you're feeling is your mind/heart readying itself for the breakup. It sounds like you are torn between dreading it and wishing to just get it over with. Maybe you don't need to do either. You know yourself and your girlfriend best, but at least consider trying for a happy medium before ending it. Of course, this is all assuming that that you are in a good and healthy relationship. If so -- then the fact that it's a hard topic for both of you, you're seeking advice and she wants to wait as late as possible could indicate that neither of you are quite sure about a complete break up. It may be worth discussing another possibility. Good luck!
