Do we break up?

Okay so, my boyfriend and I have been together for over 3 years. We started dating our freshman year of high school and now I'm entering college I'm two weeks. We've had our problems for a while, I don't want to have sex as much as him, he is socially awkward about doing things, and some more. We have fought about these things a lot and yesterday we broke up. All of the problems with the addition of me leaving in two weeks got to us and we agreed. We were texting this morning and we both feel like it's just wrong. We don't know if it's because we've been together so long or if it actually is wrong and we should stay together. I love him so much, but I don't know if I should start new at college or if we should try the distance and keep working on our problems. Any advice would be greatly appreciated
