hi! i’m not too sure how to start this off but for backstory, my girlfriend (19F) and I (18F) used to be long distance for a couple months until I moved to her state at the start of 2024. I had known a couple of her friends, simply through saying hi on facetime and whatnot. there was one friend, who I’ll call “Y” who I honestly thought i got along with, we were in a group chat while we were long distance so i figured, at least when I moved I would know more people. when i moved, we all signed up to take a class (college) together, which is kind of where it starts getting weird? Y never talked to me, despite all of us sitting in a group. if she did talk, she seemed to talk AT me or past me instead of to me. i thought this was odd but i figured maybe she was just shy or still needed time to warm up to me. my girlfriend and Y were in a friend group with another girl, I will call her S. my girlfriend invited me to go out with her, Y, and S, i got super excited about this as i saw it as an opportunity to get to know them and maybe form a bond. honestly, the whole hang out i felt really excluded which kind of made me check out of the whole situation, but I think this may have been perceived as rude. I got interrupted, ignored, etc. pretty much the entire hangout. it got to a point where Y even dragged off my girlfriend and I was just standing there alone, so I decided to walk with S. it felt a little bit awkward, but ultimately there wasn’t really anything else for me to do, i feel like? anyway, i thought this was really odd, so i brought it up to my girlfriend, so she said she would ask Y about it, but any time my name was brought up, Y would get super weird and just change the conversation entirely. at one point, my girlfriend was trying to plan another outing with all four of us, but when Y heard my name, she was suddenly too busy to be out. at this point i really thought “maybe i did something?” so i messaged her asking if we were okay, and she kind of brushed it off so i basically said i didn’t think we were and listed out a basic message explaining why, no more than 1 paragraph. this message was never responded to. i thought this was REALLY weird because I was already reaching out directly to Y, not even asking my girlfriend if Y had a problem with me. but because she didn’t reply, i simply asked my gf if she’d be willing to talk to her about it, and she spilled a lot to my girlfriend, essentially saying neither of them thought i was being left out, and them thinking i didn’t even wanna be there when in reality, i was only quiet because nobody was talking to me. after this, i sent her an even longer message literally just detailing everything i felt as a way to try and explain why it might have seemed as though i did not want to be there, why i was quiet, and i said that if she was worried, she should’ve come to me instead of only talking to S about it, she could’ve even gone to my girlfriend. but one of the bigger problems with me was the fact she wasn’t talking to me, but rather about me. after i sent Y the longer message, she texted her group chat with S and my gf, which further reinforced she was talking about me instead of to me, and she never replied to me. months after that, i ended up in the same class as her and i would hear her say my name, or my gfs name and start laughing, and i had other friends come to me and tell me that she was gossiping about me to her coworkers, so I confronted her a final time and I asked if she had been talking about me, she lied to my face and it ended up turning into a pretty big argument (i had already told my gf to stop talking to her at this point, and she did) as i was also speaking about more personal things. my gf has not spoken to her since, as i asked her to because it made me uncomfortable especially as Y honestly acted as though she wanted my girlfriend and I was just standing in her way. AITA?
