bro someone give me advice

ok so i’m tweakin. i have this guy friend who is consider one of my closest friends who i’ll call A. i know him for kinda weird reasons, he’s my ex boyfriends best friends friend who didn’t go to my school when we met (back in november) but started here in my grade two days ago. we were introduced when i joined this discord server my ex bf begged me to join which had a couple of his friends who i haven’t met irl. i didn’t crush on him originally since i met him while we were both taken and i was helping him w his gf and how to achieve his relationship goals yk??
i kinda stopped talking to him after a little argument and me and my ex broke up who i cut ties with but i heard he was starting at my school and reached out after a few months (also over discord). we started talking over summer and have rlly gotten real close since. i mean like not a day goes by we don’t message a ton plus we call every other day or so.
i have this absolutely terrible habit of (trying to) set up ppl i kinda like. i have no idea why, maybe cuz i wanna see them not like anyone i introduce since they like me?? it sounds kinda narcissistic and self destructive if it backfires, idk. this guy, A, is really into cars n f1 n shit. now i’m not, but one or my irl girlfriends is so naturally i was like “yo A, what you think of her??”
i didn’t rlly think anything would happen since im not a very executive matchmaker but now that they’ve seen each other irl, they’re lowk catching feels. i’m still working as cupid ofc since ill help if it makes them happy, but idk what to do. i keep asking them what they want to do, what they want me to do, what they’re looking for, etc as they’ve never spoken a damn word. i feel like im overcompensating by helping so hard but i can’t abandon either of them (both introverts) while they’re still doe eyed and barely into each other because they won’t do anything themselves if i drop it now. i dont know how ill feel watching my lowk crush and friend (who ill call I) date, especially if he’s into her.
it kinda hurts to think about them together even though they haven’t talked but i’m at a loss. do i stop helping?? do i confess?? do i support them both??? im so close w both of them so taking myself out of the equation isn’t an option. i’ll do what’ll hurt everyone the least, but idk what that is. any suggestions? i’m a freshman with a class of 150 so there are no other options and im stuck w these people until i graduate so i can’t do anything to ruin our relationships this early and have them pissed for for years.

help?
