What do i do now??!! Any ideas?

Ok.. So i go to this youth group and there is this guy who has long brown hair and always were my fave band's t-shirts and I really like him i always watch him talk to his friends and play the games and stuff i have talked to his friend tori a lil but to him I think I said hi and mabye he said hi to me a couple other times. I saw him at this fair with my friend Sarah but he was with all his friends and Idk if he would remember me so I didn't talk to him (i deeply regret that now) N e way, school is out now and he is older than me (by 1 year) and is moving up do a dif youth group thing. I am worried I will never see him again and I want to do something. I wont have anymore youth groups with him. but his friend Tori and i do go to the same church and for 2nd service we will be together in the main service cause she older than me 2..... Idk what to do.. Any ideas?? I would really appreciate it. I cant stop thinking bout him :( i think I might love him. and now i nvr going 2 c him again.. i can't believe i am putting this on here but here goes..
