I need serious boy help! PLEASE HELP!!!?

Okay, i'll tell ya'll everything. OK, so first me and this guy were just friends, right, so then gradualy i started liking him, i had liked him for a little more than 2 weeks when i told my best friend i liked him, she was like,"Cool!" and then after that a month ped by with me still liking him. okay so during the 15-19 week of this month we were cool and talking like normal, and then on the 22(monday of this week) he started to talk to me even more than he used to and he started to come up to me to talk which he usually didn't do and so on the 25 me and my best friend decided to tell him i was way to nervous and freaked to tell him myself so she told him. So at lunch she started to tell him, at first he thought she liked him but then figured out it was me, she asked him what he felt about me and he said,"i don't know"and had to walk away cause his buds were calling him. i get to see him between 6th period and 7th so when i saw him he waved and said"Tanya(my friend)told me,"and i waved back and said,"I know." Then after school we were waiting for our parents to pick us up from school and he came over with his friend and talked to me, he seemed a little wary of me but other than that it was like normal. I have no idea what any of what he said means and i don't know if he likes me or not(JUST TO TELL YOU IM IN MIDDLE SCHOOL!)and i don't know what to to or anything! PLEASE HELP!
