IM SO CONFUSED...? (so i'm asking help from online strangers! x3)

so like.. a few days ago (literally last friday lol) i finally got the courage to speak to a friend who had randomly started ignoring me back in september. i thought i'd ask if he's mad or sumthing and try and figure out why he's ignoring me-

so my gf spoke to him, told him i wanted to talk, he was like "ok" and then a bit later i went up to him... and he just like. turned away and left? like literally just dropped his bag, walked away and left me standing there with his group of friends around.

me, my gf, and her friend just stood there in disbelief (they were laughing, i was just like "huh??????") and then i noticed one of his friends suddenly getting called while most of his friends stayed there and i literally saw that friend of his looking over at me while calling (i'm p sure my like old friend ig was calling him) and i was so confused..

and then later, i see his friends constantly looking at me, literally gossiping about me, i hear my name being said by my old friend- but he won't ever look at me, or atleast not while i'm looking.. his friends always alert him when i walk past, that kinda thing.

btw i should mention this guy is reeaaallyy social (has way too many friends and talks way too much) and seems to be scared to talk or look at me (some neurodivergent introverted ass girl who dresses pretty emo n stuff)- and he usually doesn't really ignore people he hates either, he just acts neutral towards them.

so like- what the hell does this dude think of me? does he hate me? like me??

i'm sooo confused, but i guess i'll see how he is at school in like nearly 7 hours LOL
