Ugh this annoys me..

So I'm 17 and my boyfriend is 19,we have been together for 3 years. He comes out every weekend and stays the weekend and everytime he just wants to stay inside. I ask him what are we gonna do because he has his own car,and he says staying home. I'm stuck home all week and never get to go anywhere and he knows this.. It frustrates me because I actually want to do something,I'm tired of being home and I don't know why we can never do anything.. He works and has classes but he only works Tuesday and Thursday and maybe the weekend and has like 2 classes Monday,Wednesday and Friday..
