He's gone away to college

My boyfriend and I started dating the middle of my freshman year right after new years and now I'm a junior so he just graduated and is currently away at college. Me visiting isn't really an option right now and he's to busy to really come back, the school is 4 hours away. Any suggestions or experience? I know long distance is hard but it seems like we fight more and i don't feel as loved because the communication is lacking alot on his part.
