What should i do about my busy boyfriend?

My boyfriend works 5 days a week, pretty much all day long. So i only get to see him twice a week, and the days that i do actually get to see him are on the weekends. Since we are still in highschool, usually he just wants to go to a party with his friends and he takes me with him, but i would rather spend my time with him alone. I have told him i feel left out, and we never spend quality time together, but it hasnt changed anything. What should i do?
