Why won't he accept my friend request

I don't know him very well but he came with my youth group to a camp, he is really cute and was born in the same year as me (2001). I've talked to him once or twice and so has my sister who is 2 years older than us(1999). He sent her a friend request and she accepted it and I sent him a friend request and he never accepted it. My other sister whom has never talked to him sent him a friend request after me and he accepted her she is a year older than me(2000) he hasn't declined me but never accepted me. He is friends with all my friends on Facebook as well. The worst thing is my family thinks my sister likes him (1999) but I do and it's making me feel like crap
