What do I do?

I've been with my boyfriend just over a year and a half and I'm so happy I met him but I'm really struggling with the distance. I don't cope well with stress and lately we've been arguing a lot and I just don't know what to do. I don't think I could live without him however its becoming increasingly difficult to cope with the distance. Also when we are finished college we were planning on moving in with each other (as that's in 2 years time) but I want to stay where I'm from as does he. I tried to compromise and say we could live somewhere in the middle but I still don't even think I could bring myself do to that. I want nothing more but to stay with him but its really difficult to cope as we live at opposite sides of the country and be hardly see each other. What should I do?
