My boyfriend has very little time to spend with me, how do i deal with this?

i rarely see my 21 yr old boyfriend of 2 months and when i do see him im still pretty shy with him. He works 5 days a week now because he took weekends off just to spend it with me. But sometimes hes even too busy to see me on the weekends doing other things like just this past weekend he worked on a roof. the fact that he lives a little over an hour away doesnt make it any easier. during the week he works all day, showers, eats, and does stuff around the house for somebody else. he was raised to be a hard worker and i understand that but im getting quite lonely and i would never consider dumping him. im 18 and i was even offered to move into his brothers house down the street from his parents house (which is where he lives). but ive done enough moving around and im afraid ill move in there and ill just hafta to move out.
