Guy help soooo confused!!!?

so there is this guy i met 2 years ago and we were in the same class he seemed into me cuz he always talked to me and we used to kick each other playfully and once he looked me right in the eye and said ur awesome will u go out w/ me? then he looked away shyly i thought it was just a joke and he always asked for a high five and he always said my name repeatedly and he kept trying to figure out where i live. So i sorta liked him but it grew to me liking him a lot. so now 2 years later i still lik him so i asked my friend to ask him if he liked me but he said no but during cross country he talked to me n stuff then later in the year i sent him a cookie for thanksgiving (this thingie we did in school) then at the end of the year he asked my best friend if i liked him so she said i dont know ( she did know) then consulted me i told her to say yes but then wen i went to spanish this girl i hate was making fun of me for liking him and i was lik why would he tell her? turns out he told this one girl who is his close friend who told the girl ihate who is her BFF. I know he didnt mean for anyone to know but then my friend told him i lik him then he said really? (he was sorta shocked) then he said i like her as a friend. Then i told my friend to tell him i dont lik him anymore then he was like YES!!!! she doesnt like me anymore and his fists were in the air and that made me feel so bad. then he went to this random dude and was like u know tat small girl? she doesnt like me anymore!!! tat made me feel bad it broke my heart cuz i still liked him then wen we went on this field trip after he found out we were in line together i was hiding behind my friend and he was like hi heyy (my name) a bunch of times and he also called me by my nickname the class made for me 2 years ago(none uses it much except him) he kept trying to talk to me but i was hiding from him then i finally gave him a little wave and he was like yes! i grabbed my food and ran away he made me feel soo akward. then i told my other friend about it so she wrote him a note saying to leave me alone and that i dont like his nickname (but i do still getting over him) but after he got the note he was lik HEY (my nickname)! then he was like see ya (my nickname)! cuz it was like the last day of school. now i am confused cuz he seems lik an a**hole but maybe i thought he liked me or ppl change idk how do i get over him? and does he not lik me really? sorry so long but THANKS!:)
