Dating help needed please?

I am on my dads account cause i am grounded from my mine. now i need help!! there is this guy, a grade older, who is in math club with me...i am in LOVE with him. I cant go two cles without seeing his face. today we had all math club members called down and when i got there he came up right behind me and said "Hi bella" and i was like "hi edward" ( not our real names) then we didnt talk. then, he asked if he could go to the bathroom rite after i said hi. he went and came back reely quick and was fixing his hair when he came out. then he stood next to me and i moved over to my friend. he stayed there, but slowly he worked his way over to me. he was moving as slow as a glacier (no lie) and i didnt notice he had moved till he was RIGHT behind me. does he like me????? also, on dec. 4, we are all staying after school...and i just realized i would be spending like 2 hrs with him and potentially waiting for a ride while he is. wat should i wear, wat should i say? he is real simple. short blond hair reely cute...he wears one sweatshirt (but a diff shirt under.)
