i need help :/

so i’m 15, a freshman in highschool and i’ve been talking to this guy, whose 16 and a sophomore in highschool, for about a month now but we haven’t told anyone bc i don’t want to. i don’t want to get judged bc the people i hangout with are perfect and get all good grades and homecoming court and i’m just like them but the guy hangouts with different kids and people tell me like don’t care what anyone thinks but it’s hard because i know i’ll get judged and it’ll be too hard for me to handle and i’ll want out of the relationship. so idk what i should do.
