Does this guy like me??????????????????

there's this guy who i have every class with we flirt but i never thought about it until by friend told me that he has a crush on me and it's pretty obvious. it's the little things, were band geeks and he's always posting songs on my wall that he wants me to learn so we can jam together. today we had to clean out our lockers and i was running down the halls because i forgot to get my lock, he was in a group of friends (10 people) and i asked if someone would like to come with me. he was the only one who said yes. he's always taking the dividers in my binder. and he's a really nice guy. the only problem is that i have a thing with another guy and 2 of my friends like him as well. :(
