I really need help with thiss..?

theres this guy i like, and he flirts with me alot, but i dont know if he really likes me. im much too chicken to ask him myself, he doesnt have internet so hes very rarely on AIM, and im not gonna lie, having someone ask him for me seems kind of babyish. but hey, ill do it if its the best way. what should i do? is there a way to try and find out without me or someone else asking him directly? whats the best way to find out? please helpppp!! thanks..
