FUN ideas to spend time with my fiancee!!! please help!!?

I've been a little bit more thean a year with my now fiancee...we always enjoyed our sexual life...we actually do till now!!...It's just that sometimes he wants us to spend too much time with his "family" (aunts and uncles) because they get together EEEEVERY saturdays evening and all sunday...He works monday through Sat. till 8 or 9 pm.. sometimes even sundays till 5pm (that's not always)...so we barely have time to spend together and i wish at least we could spend all sunday together instead of with his family every weekend. Since we are from different cultures I have a lot of uncommon things with his family. I respect them and always be gentile and educated with them but sometimes I fell like they try to study every word i say. Anyway, I'm getting tired of this situation and I wouldn"t like to break up with him because we LOVE each other, but I just want to have one on one time with my love!!!..Please tell me fun ideas we could share as a couple...I'm 22 and he is 23...we turn 23 and 24 in July. PS.- we do things like go to the movie theater, dancing, or watch a movie at his place or mine...but we've never gone to play pool...I'd like to though...so just ideas like that I would reallly appreciate...THANK YOU IN ADVANCE!!!
