Hi. It's 3am in the morning. It's on my mind and I can't sleep, so I'm here to type my frustration away. Thank u in advance.
My bf (24M) and I (22F) have been together for almost 3 years now. He has 3 sisters, all of whom was shy to interact with me at first, since I'm his first ever relationship. Today, the older 2 sisters, 19 and 14, are as chill as an ice cube with me. The youngest sister though, C (13f), she's a different story. She was the most aloof when we first got together. Over the years, C and I were neutral, I came over to his house a lot, cooked for the fam, we bought C her dream kpop light stick for her bday and more. Point is - I tried. Anything from small talk, to spending more time, to inviting her out, to gift giving. She's always been "meh" about it, but hey, I'll take the tiny progresses. [ a bit of background about C: She grew up the youngest in a house of 5 children, her parents never disciplined her (sources are from the people living in this house themselves) and she has a history of yelling, stomping and slamming the door at the parents' faces when she doesnt like something. This is all recent and still happening btw, not 3 years ago one time incident. I hope it gives insight on how she normally behaves to everyone around her...]
However, recently, barely the past 6 months, we all feel like C doubled down for the worst. the vibe just changed, it went from neutral to hostile. Lots of passive aggressiveness, shes just straight up a b to me. - when we go out with just the 3 of us, me, bf and C, she'd only talk to him and exclude me. Every time we try to bring the convo back to being 3 people, she'd shut down, ignore us, then just pick up at where she left off with my bf. Even when I chime in, she'd go quiet, then just ignore it and continue talking to bf like I'm not there. - when we go out in our fam group, with all 3 sisters, bf and me, C would go into wall blocking mode. Every time bf turns his back to look at something, she'd scoot right in between me and him, then just walled me off. The entire night lol. - I'm fortunate enough to have a company car and gas card, living in CA, I always offer my vehicle whenever we go out, its a better economical choice. But I need a headcount of who's coming for insurance purposes should something happen. Well, instead of talking to me about wanting to come along, C basically snuck herself onto my car. She knew about the plan for days, I was in the same living room as her for the entire night, instead of talking to me and asking to come along, this kid just snuck onto my car and saw nothing wrong with it. We were waiting for her to ask to come along too. Nope. Nothing. She ignored me the whole night, then she walked in to my car like she owned it lol. That was the last straw for me.
Listen. I'm just frustrated and tired. I know she's being petty and bratty, but I wasn't going to enter into a cat fight with a 13 year old when she did that shitty jealous gf walling off move. Its comical as much as it is frustrating. I kept on thinking how she resembles every bad trait of the Kardashians girls growing up, turned out, she binged the show this year's summer and that was when her attitude has changed. Now She's entitled, disrespectful, mean, and just straight up a b word. She's not just mean to me, she's rude to everyone else too. The other 2 sisters talked to bf and I about it, bf and I also tried to talk a lot about it. I think the turning point for my bf and the 2 older sisters happened when C mocked of a haunted house actor for his profession, after demanding for everyone to go to the haunted house. From there, everyone has just been on the fence about C. They're convinced she just became a melting pot of all the Kardashians after the binge.
So, we are here. Bf and I talked a lot. We agreed on a few things we could say and do to combat her passive aggressiveness when it happens again. But im mad. I feel like now the responsibility falls on us to "fix" her and make her a better person. I know my bf is feeling that pressure. Their parents are done, they don't want to do anything anymore after all the drama and slamming doors, they just let her be. The other 2 sisters ignore C as much as they could now. She's just so very unpleasant to be around. I know I'm nothing to her, so it doesn't matter what I say, she ain't gonna listen. Bf tried talking to her though, blessed his calm heart he really tried, from pointing out her behaviors to just dropping a truth bomb that she doesn't have much friends because she's been acting like this. Her reaction is usually going quiet, walking away and locking herself in her room; when she'd emerge again, it was as if the talk never happened. She completely disregarded all of it and never addressed it. Every time she doesn't want to hear something, she just goes away. And just like that time goes on and it's been months of her being like this.
So yeah. Idk where to go from here. Keeping distance from her is ideal, I honestly have been doing that, until she invited herself into my vehicle. Bf does see the problem and he's troubled too, he doesn't know how to deal with her either. On one hand, we agreed that we have enough problems on our hands, we don't need to invite more by "fixing" her, it's not our job; but on the other hand, I do understand the sibling love, he worries for her and he just wants her to become a better person. But how do we communicate that with her when she's like this?? I don't think anything would go through to her thiccc skull right now.
Tldr: Bf's little sister turned into a jealous gf/sister against me after 3 years. I'm frustrated because it's literally not our job to "fix" her, all while she's doubling down on being a brat. She's not listening to anyone.
