Does he like me or is he just being really mean? please help me?

that is sooo cute! Your friends are correct xD he DOES like you. Seriously, why would he single you out to go over to your group to say some meaningless "gay" stuff. Guys are really weird. He does like you. :) Dont worry too much about it. If you like him back, tease him back. Since Halloween's coming up, try trick or treating together. It'll be fun.
