Okay first off I know that sound bad but i promise it’s not what it seems. Ok so I (17 f) have been friends with this girl I’ll call her Emma, since elementary school. We weren’t really close until last September her father passed away from cancer so I came over to her house every day for over a week and we became really close, I also became close with her two little sisters (14 and 9) and also became close with another two of her friends we’ll call them Rachel and Shelly. I knew Rachel from a young age but she was really mean to me as a kid. One night I called Shelly as I did a few times that week because I knew she was going through her own grief and Emma was out of the country for a family vacation for three weeks. I called Shelly through Instagram facetime as I didn’t have her personal number and I posted on my private story a picture of us on FaceTime (as we did something funny and shelly requested I post it), Rachel saw that picture and texted me to add her to the call so I did and she talked with us for about an hour. Later this guy texted Shelly and she thought he was really cute and she noticed he’s from the same town as two other friends of her (two friends that were in a fight at that time) so she tried adding them both to the call but neither of them answered so we decided to end the call as they could all join and we didn’t want them to face each other (the two friends that were in a fight). However in FaceTime calls on instagram it opens a group chat with all the members of the call automatically. Me and shelly continued a new private call for another hour and during that hour one of the two friends texted on that gc and asked what’s going on so we took the opportunity to ask her if she knows that guy and that was the ONLY three sentences of a conversation that was at that chat and I archived that chat after the conversation ended because i barely knew the other girls and wasn’t planning on saying anything more in that group chat. The next morning I woke to angry texts from Emma saying she doesn’t want any contact with me, that I’m not allowed to contact her sisters and that I was really nasty for what I did. I was obviously very confused so I asked her what happened what did I do. She responded with “you opened a group chat with all my friends and did not add me” so i immediately tried to make sense of it all and i figured out because i started the FaceTime call it said I opened the group chat so i started trying to explain it to Emma that it wasn’t what is seemed but she was so angry she didn’t listen. I’ve gathered maybe I should wait a few days for her to calm down then texts her as she was supposed to come back for her vacation two days later. I also asked Rachel and Shelly if they know what happened and Rachel responded with “I added her to the group chat in the morning and told her that yesterday in the call I asked if Emma can join and you said she was asleep. Also don’t bring me into your mess I was only in that call for five minutes” which was a complete lie. Shelly and I can both confirm she never asked about Emma in that call and she was there for over an hour. I know I might sound the asshole for not adding Emma to the call but it didn’t even cross my mind as I didn’t want to disturb her on a vacation and I knew it was already past midnight where she was. A few days later a sent Emma a long message explaining everything from my perspective but I also included an apology saying I know it looks bad and I own up to it but it wasn’t my intention, she sent me a short reply saying I should “stop blaming other for my mistakes and own up for my actions” for that I know she didn’t even read my messages, I told her I’m sorry again and said I explained everything from my side but she haven’t responded to me since and the other girls don’t talk to me either. I do know she came in terms with all the other girls but me and has not replied to my texts since and that was over two months ago. So, AITAH?
