am i overreacting?

okay so to start off with some background information, we’re both guys (18) and in highschool. we label our relationship as “best friends” but he’s given me so many mixed signals that are clearly romantic and not things friends just say. he knows im bi, idk what he is but he usually has portrayed himself as being straight in past conversations. im not 100% sure tho since he does give off that vibe of being part of the community but not fully accepting of himself/internalized homophobia based off of all the things i’ve picked up.

anyway, my point is, he always walks with me during passing periods and we even go home together. he suddenly stopped doing this a week ago so i asked him about it and he told me it’s because people have been spreading rumors and making assumptions about us being a couple, so he backed off away from me. i UNDERSTAND him, i get why he did it, it’s 100% valid. but it did also make me feel like a freak that hes embarrassed to hang out with. im not blaming him, jm not immature. but im just a little disappointed in him listening to them because trust me if you see the way he acts with me it’s clearly not just a friendship. now i’ve also distanced myself and ignored him because i got mad about the situation, and whats even making me angrier is when we discuss it, he says im playing victim and says “why are you so mad” and all of these insensitive things. he even said that i have my own friends and he has his. like obviously, i never denied that??? but why are you acting like we were nothing??

omg he makes me feel like IM the crazy obsessed one but just weeks ago he was saying he loves me and that im pretty and that he wants to hug me like what??? obviously i’ll expect us to always walk after u say things like that? it’s called recognizing a pattern and expecting it and obviously one will be frustrated after it doesn’t happen anymore. im so done. like am i in the wrong/overreacting for this
