AITA for finally calling my ex best friends out on their behaviour?
So for context I (17F) met my now ex bff who we’ll call Red (17F) in 2021, we had both joined a new school and we only had 2 friends, her friends were cousins from the same family who went to her primary school and I had only just made friends with these two friends who knew each other since year one. When we met we both talked about anime and manga, yes we got called cringe for our interests. After a little while our friend group grew with me meeting my now gf (16F) through another old friend of mine, she introduced me to another girl who we’ll call Ret and invited her, my now gf and her friends to sit with us, she agreed and our friend group was great. Last year we met a guy who’s code name will be Greg (17M). Now before I get into the nitty gritty details about how we became ex best friends I want it to be CLEAR my gf and I had the same interest and bonded over a game and we kept binding ever since to the point where in December I nervously asked her out and she said yes, she understood me on so many levels and knew how to help me when overwhelmed. So on the 19th of July of 2025 I got a call from Ret, I went over to my phone as I was cleaning and picked up, I couldn’t see where she was as all I saw was her face and a light from behind her so I thought she was at her place, we chatted and she then said “stop saying Melissa” I was confused and thought her sisters were teasing her, but when she panned the camera over it was the whole friend group minus me and my gf. I did have to go off camera a couple of times as it hurt that I wasn’t even asked to hang out, no call, no text and no snap and group chat. Fast forward to September and the same thing happened on Reds 17th, I was hurt my on best friend didn’t invite me to anything. When I brought it up she said “they had never been to my house” & “oh well the concert was like £30 per person and it was super loud” for clarification I have ADHD and autism, however I know how to calm myself down before I have a shutdown response. I was still hurt about it and decided to distance myself, which was when I noticed her behaviour, I had gotten an essay sent from Greg’s phone but it was all coached by red, it was calling me a bad friend and how I didn’t listen to them when they brought up my behaviour in the past. They actually never talked to me about it, they never said “oh your behaviour isn’t the best right now.” In the message Red took it upon herself to ASSUME stuff about her friend of 4 years, a girl called Haley had passed out in the schools out door seating area, I said I hope that she was okay as I know how it hurts to pass out and hit your head. However she took this as me making it about me, all I said was I know how much it hurts, nothing else about me passing out or saying how I had passed out months prior. When Haley came into class I asked if she was okay and sat with her the whole lesson making sure she wouldn’t pass out again. Here’s where all the behaviour Red “called me out on” became obvious, she continuously interrupted people to talk about herself; one day I was talking about my little brother and his birthday which was that day and before I even got 3/4 of the way through the conversation she interrupted me to say how she was born 9 days before her mum. I already knew and I didn’t ask her about it, she brought up my little brother and I was talking about him being happy. I also learned from my ex girlfriend who occasionally talked to Greg that the reason why Red didn’t invite me to her celebration at a concert was because she stereotyped me into what is considered as “childish autistic behaviour” and said I’d ruin her birthday with a “meltdown” as I said before I have shutdowns, and either way I ended up “ruining” her birthday even though I wasn’t there. I eventually confronted her and she denied ever doing it and now I’m contemplating to write an essay to her calling her out, and blocking her after our prom. Now she’s going around spewing more lies about me so ATAH for actually calling her out?
