So my boyfriend and I met at a New Year’s Eve party in 2023, right before 2024 began, the party was being thrown by his best friend, who I had mutuals with. That night his best friend proposed to his girlfriend, later I found out they were on and off for 4 years and she forced him to propose by January 1st or she’d “leave”. The 4 of us started hanging out a couple weeks later and everything was fine, but I did notice her mood shifting a lot, she’d walk to the other side of the room, bonfire, etc to get away from her fiancé, and sit there with a bad attitude or randomly cause irrelevant problems, usually bc she wanted to go to the bar. She started to say stuff like “you can have this ring back” or “if the wedding even happens” and in front of his friends and both of their families. 

We went to the bar one night and she started accusing him of “thinking about another girls a$$” who was also at the bar, but minding her business. I guess she was just insecure after seeing this girl, but her fiancé got upset saying “you don’t know what I was thinking I wasn’t even looking over there”, he was clearly confused. He goes outside with my boyfriend and this guy comes up to me and his fiancé (f21) this guy is probably 45-50, apparently they are “friends”. She starts venting to him about her fiancé “thinking about another girls body” when she’s “right here and all natural” the girl at the bar was natural, she was clearly just jealous of a stranger. So the 45 yr old dude says “I would never treat you like that I’ll get you pregnant tomorrow “ she giggles and he continues like “no seriously I’d put a baby in you now”, and she just laughs and continues to enable it. I told my bf, he told his friend, he didn’t care and still allows her to hangout with that guy. 

She started to say stuff about my family. Saying my mom has herpes and she knows this bc apparently she knows my moms bf, then she says she saw my brother cheating on his gf at a bar (my brother isn’t even 21) and she starts talking about the way I dress, how I’m smaller than her, death staring me when I’m playing games with my bf and her fiancé, doing nothing wrong, but yet she will flirt with my bf in front of me and stare at me to try and get a reaction, or tries to openly make fun of me in front of people. Making up weird lies all the time about anything and everything. One time she asked my bf how much he made so that she could tell him she makes 85,000 a year, he laughs, she goes to the bathroom and her fiancé walks up and my bf says “hey she just told me she makes 85,000 a year” and her fiancé was shocked and was like “that’s a fcking lie”. Always trying to get into physical fights with random people for no reason, even men. Another time we went to a concert and the boys went to get drinks and she said “ya my fiancés a whore” I said why and she “said he had a threesome”, when they came back I said did he have a threesome and my bf laughed and said what no, then told his best friend and ofc he didn’t care about another one of her random lies, even tho she was trying to make him seem like a bad dude. 

She’s always talking at me trying to “give me advice” but she’s just preaching at me every time I see her, not letting me talk, and saying things that are so off and wrong. She’s not older than me, nor am I lost in life, so i don’t know why she feels the need to do this. One time we went to a carnival and she got drunk and started comparing our relationships in front of her fiancé saying “it must be nice to have him do stuff for you” and “I had to pay for everything when we first got together” bc my bf bought me something, I awkwardly laughed and looked over at her fiancé who looked super hurt. She’s always forcing people to go to multiple bars in one night, even if you communicate you have work In the morning, you will just get laughed at, I don’t even like drinking or going out so we just started bringing our own car to hangout so we don’t get caught up in any bs. Another time when we went to a bar, her fiancé went to the bathroom and she told me and my bf that she had an abortion when she was 17 but to never tell her fiancé bc he will freak out, obviously my bf doesn’t like her and has been best friends with this guy since they were little kids, so he told him. But this guy will never leave her, even if she cheats on him. My bf said it was either his baby or she cheated so either way it’s a lose lose bc she kept something huge from him. 

Another time we went to a friends house and my bf recently bought a house so they were asking him about it, he said the only thing he wish he could’ve done different was take me to look at the house before buying it bc I would be living in it, she starts saying there’s nothing wrong with your house, and I chimed in and said “yea absolutely not I love the house”, she completely cut me off and ignored me, standing across the kitchen island from my bf she locks in on his eyes, not acknowledging me and says “don’t worry about anyone else. This is your house. Your money. Your credit. Your name on the lease. Seriously dont worry about anyone else, you’re the one who worked for this” mind you, I live in this house and do my part, she keeps going and I’m leaned over the island a couple feet from her starring at her shaking my head. Her fiancé saw me getting angry but no one will tell her to shut up, ever, even when she desperately needs to. I’m proud of my bf but he doesn’t even like her they aren’t friends and he begged his best friend not to propose to her before we met, so she’s basically always crossing a line. He was also talking to his best friend, and just saying he wishes he took me to see it. My problem is that she made me out to be something I’m not, and I dont even bother anyone when im around. 

These past few weeks she’s been having family drama. One of my bfs other friends is dating her older sister, so it’s a friend group with family ties. We all hangout and we went over to the other guy friend and sisters house, after my bfs best friend and his fiancé left, her sister began to confide in me. I didn’t know they were having issues until this, but I wanted to validate her feelings so I told her that I also thought her sisters behavior was off putting and disrespectful. My bf and his friend came in and started to also talk, but they rlly don’t like her so they went off, and her sister shut it down once it got to a point of “sh*t talking”. So my bfs best friend and the other friend dating the sister work together, and he was trying to “talk sense” into him about his relationship with this girl, and told him about all of us, even her sister, talking about her behavior. He went home and told his fiancé and she said she felt disrespected bc she always “tries to help me.” I don’t ask for it, or need it… I honestly let her talk bc it seems like she needs it… He called my bf and told him hey I know about y’all talking shit and my fiancé wants an apology from your girl bc she’s always tried to help her and my bf said she’s disrespected her so many times and her calling out her disrespect ismt disrespect. 

The other guy friend and his gf (her sister) came over to our house a couple days later and apparently they all got in a huge fight and he doesn’t want to be around her anymore, even if it is his sister in law. My bf keeps trying to hangout with his best friend, but every time he says his fiancé is gonna be there too and says bring your girl, I don’t feel the need to hangout with her, especially now that she knows I don’t rlly like her. I wish his friend would just hangout with my bf, but he’s so whipped, they haven’t hung out alone since they got engaged on new years. If I do see her I won’t be apologizing, I don’t think I did anything, I kept my mouth shut for over a year bc I didn’t want to spoil my bfs friendship. I could’ve told her off the first time she disrespected me, but Im not engaging in her bs.
