I (18F) went to a concert with my best friend (also 18F) last night. it’s important for me to mention that she paid for the tickets. and her mom paid for the hotel. for context my bsf didn’t ask me if she could invite her boyfriend (18M), but instead she just told me. a made a post on here explaining the details of that conversation asking pretty much the same question. i hadn’t met this boyfriend beforehand and i knew absolutely nothing about him. me and my bsf are long distance so i don’t get to see her as much as her boyfriend would. when we had the initial talk about her inviting him one of my main concerns was her making me be left out and third wheeling. she swore to me that it would not happen and i believed her. Flash forward to last night. exactly what i thought would happen did infact happen. she made me third wheel the whole time and i felt like i was just in the background to her. majority of the concert i was trying to get her attention and trying to get her to dance with me and everything. she would. but then her boyfriend would catch her attention so she would mainly focus on him. he was holding her the entire time and they sang the songs together. even a song that was mine and her fav song. she did say “i’ve been trying to make sure you don’t feel left out, so i just check up on you every few minutes” which in other words (to me atleast) is “im here with my boyfriend and i just want you to think that im giving you my full attention when im not” after the concert we went to the bathroom together and she said “i hope i didn’t make you feel left out” and i said “yeah but that’s exactly what you did though. you gave your full attention to him and barely even talked to me. this was supposed to be a thing for us but you HAD to invite ur boyfriend” and then she followed that up with “yeah but neither of us are really touchy people” after she said that i then went into a stall and a few seconds later i hear absolute SOBBING coming from her stall beside me. like crying i’ve never heard before. now we are back it the hotel. she hasn’t said a word to me. and i don’t overly know if i’m the asshole for reacting the way that i did. sooo AITA?
