I'm in a long distant relationship both at school and even at home

I just got back from school yesterday. My boyfriend is 8 and a half hours away from my school and 3 and a half hours away from me at home. We've tried to see each other on several occasions during the school year but his job puts a huge burden on our relationship and often requires him to work on the weekends. I've tried to go to him on a few occasions but have failed as the result of his job and its ridiculous demands and vise versa. We were supposed to spend this weekend together but on Friday he told me he was unable to drive down to where I live bc of his job and his car transmissions stopped working. I would have taken a bus to see him but I have a prior commitment this weekend that prevents me from leaving my home. What do I do? I told him how I felt and he said he's being doing a lot of thinking after what I said and didn't know where to start. I do not want to break up. I really care about him and this summer was supposed to be our summer where we'd get to actively spend time together and it's starting off completely on the wrong foot. He's such an incredible guy. We've been together for a total of 9 months now and last week really taught me just how fortunate I am to have him in my life even though he's not physically there most of the time. I really want this to work and even though I know I'm being stretched out thin. I'm just scared of starting over. PLEASE HELP ME!
