I'm confused

Kassie • High school senior/college freshman. In a relationship
So I'm with my boyfriend and he's honestly the greatest guy ever. He's patient, kind, caring just the sweetest guy. He's older then I am and we've been dating for a year. 
But the thing is I'm going off to college and I've just lost that wanting to be in a committed relationship but at the same time I want to be with him cause I really love him. I waver between there two feelings constantly and I don't know what to do. I can't really figure out what I'm feeling or what I should do about it.
