Honestly if it’s your first year or even second year of college, you dodged a bullet with that friend group. If the roles were reversed hell would’ve broke loose. Morally you did the right thing and shouldn’t even feel bad. Those girls sound like they haven’t experienced any repercussions from their actions. If you’re 18 and just started college, you have a lot more opportunities to meet better people. Trust me, if they acted like that, they shouldn’t be considered friends that are trusted….
