There is a boy who is in my geometry class (i'm a sophomore) and i am not sure if he likes me! I like him &

Well today, we both stayed for final exam review for another class, we have the same teacher different periods. he seems to be droping hints but i don't know if it is little things that i make a big deal out of. today, i went to look over at my friend and he was looking at me and i looked away! and then when the teacher asked something and i got it right i heard him say something about me being perfect. and ppl started leaving bc it was getting late and it ended up just being me him and the teacher. my mom called me bc it was getting late and after i hung up he said that he doesn't get service in the room so i said that if you need to call some u can use my phone and he put his number in my phone. then we left together and talked & he asked where i was going. do you think he likes me or just wants to be good friends? also, this summer me, him and 3 other ppl are attending a 3 day leadership conference, what should i do, i am not the type to tell him straight. sorry it was so long!

Hm. In my opinion, I think he takes an interest in you. Not sure how interested but he obviously wants your attention. He may just think youre a cool girl but as I think about it, Im leaning toward the "he wants to get to know you better cos he likes you".
I would just take things slow, dont rush into it and be like " OMG I LIKE YOU." Keep him guessing. Plus, guy friends can sometimes be a lot better than girl friends. :]
