Relationship?

I've been in this relationship for almost 1 year and 8 months, we have had great disagreements about various things but mainly about trust. Well now we're off to college... he's going to go out of town because of his football scholarship and I'm attending one here at home. Remember him and I have had great disagreements and it involved trust, I told him how I felt and how confused and frustrated I got when I thought of it, of course he turned the table on me. He went on, but the one thing is that I'm really the insane jealous type of girl, and I want to be able to go to school and focus as well for him.

What should we do? We both want to graduate and start our lives together but college is really making us want to drop it and see what happens... HELP ME ITS FRUSTRATING!
