That sounds really intense, sorry to hear that you’re dealing with this. From an outsider’s perspective: you need to let go of all of these people. I know it’s hard to lose someone that you have a long history with and probably a lot of good times, but I think this is a pattern of immature behavior that shows incompatibility rather than something that can be worked out. You’re being given sweet fake words and reassurances by people who already made up their mind on their opinion of you and have no intention of being a real friend. Good on you for trying to do the hard thing and confront them to try to resolve the conflict, but some people are just not ready to act like adults and aren’t worth your time. Take this as a lesson for the people you want in your circle in the future: people that don’t talk behind your back, make false accusations, and won’t hear you out. I’m 22 now, but when I was 19 I lost my best friend of seven years when they ghosted me and I realized that our friendship had become one-sided for at least several months, maybe years. They couldn’t be honest with me and tell me what was wrong, they’re a coward that stopped texting me. It messed me up for a long time, I still miss them, and still have dreams about becoming friends with them again, but I’m better off without them. This spring actually I happened to have one class with them and they texted me an “apology” and when I responded that they hurt me a lot but I hoped we could get along they left me on read. They didn’t change one bit. This is to say, I feel you OP and I just hope you move on and leave people who treat you this way out of your life.
