i have done something really shitty not inexcusable but shitty and atm my entire friend group hate me and idk what to do they won’t speak to me and it’s causing sm stress i really need help on how to apologise because i’m kind of bad and i love them all so much i just fucked up

what r the best tips on apologies and how to?

basically we r in school and a guy who is also my friend touched my friends boobs (by accident) and it made her feel uncomfortable and they were trying to get the police involved and i said to them to not do that cause it could fuck up his entire future and now they think i’m defending him which i’m not i just don’t want his life to be fucked up and none of them will speak to me (that’s the basic context)
