mixed signals

so, there’s this guy that like my best guy friend. recently, i saw him staring at me in classes, starting a LOT more convos w/me, and just being extraaaa friendly 😂 some of my friends say that he likes me and that he might ask me to hoco but i’m not sure. last year, he told me he likes this popular girl and i’m not popular in that way at all 😂 why do u guys think? did his feelings change?
