Boyfriend of 2 years moving

So my boyfriend and I have been together two years. We are both in college and currently live an hour away from the junior college. He just recently told me that he plans on moving to the town our college is in, Tyler, to save diesel and money and wants to get a job in Tyler and come home on the weekends. No I'm not moving with him. I'd see him on the weekends. I'm a nervous wreck honestly. He lives 20 minutes away currently so that's not a big deal but I'm scared for when he does move the hour. As of right now, we argue because when his bestfriend comes home from the rig every two weeks, I'll see him maybe twice a week but the two weeks his friend isn't here, I see him everyday almost. (My friends have all moved away for college) It makes me nervous that he won't make time for me. Maybe I'm over attached? I need advice, help, on how to solve this. I know it's my own issue and I can't hold him back from doing what he wants and needs and I don't want to. I'm just terrified.
