Does he like me?

on msn messenger i asked if ill ever have a chance with him and he was like what do you mean and i told him just tell me straight up if i ever have a chance to be with you. it took him about 7 minutes to answer (i gess he didnt kno what to say) he said idk what can happen or what will happen, but right now i dont rlly want a gf -(i kno this is tru that he doesnt want a realtionship bc he told someone else this the same thing- theres too much tto do rite now. he doesnt kno that other person told me) he always sends signs he likes me: always catch him staring is the main thing- whenever we p in the halls to say hi he always grabs my arm. im always the one to msg him first though bc hes really shy around ONLY me. we've hung out before but with a group of eachothers friends, and wen i told him i liked him he thought his friends were playing a joke on him (bc im good friends w/ one of them) ! (mayb it was 2 good to be tru?) everyone says he likes me, but idk - hes scared to have a gf :(
