long distance for four months

Me and my bf met in college. We just moved out and now we live four hours away from each other. This boy is my first serious boyfriend and I like him SO much. We took each other’s virginity (which means a lot to me, I was saving it for the right person). And last I saw him was Wednesday- it is now Saturday, and I miss him so much. Our work schedules never line up so it’s hard to make time to see each other even though we are both willing to drive the distance to see each other. I am so scared that the distance will bring us apart and four months is such a long time. How do we make this work? :(
