25-year-old brother's girlfriend tries to kick 15-year-old out of her own house that the siblings together, saying they want their own "space": 'I reminded her that I own half of this “space” so she’s delusional if she thinks she can just get rid of me'

When you're in your teens and early 20s, your partner's little siblings are either the most annoying or coolest kids you know. Some of us probably even ended up like them more than our boyfriend or girlfriend, after the inevitable breakup. But no matter how much you like them or get along with them, there is going to come a point where they've been a tag-along one too many times, and you find yourself wishing that they could find something else to do so that you could spend some time with your spouse without them around.

Still, it's kind of hard to tell your boyfriend's younger 15-year-old sister to get lost when she part-owns the house that you're trying to move into with your boyfriend. At that point, there are other considerations in play that you need to be mindful of. Sure, your boyfriend might be her guardian, but as such, you wouldn't be trying to kick any other minor who your spouse was responsible for out of their own home and should probably be approaching things with a more mentoring and caring mindset.

That's the situation that this 15-year-old girl, who lives with her 25-year-old brother in the house that their late father left them, found herself in when she came into conflict with her brother's girlfriend, who seemed to be looking for ways to get her out of the house and out of the way. And we're not talking for the evening so that the pair could have a night together without the little sibling around, we're talking for good.

It started with vague insinuations about how the 15-year-old should begin attending a boarding school before moving on to a university in a different city, clearly trying to clear the way so that she could move in. Frustrated, the teen shared her story with this online community wondering what she should be doing.

    "AITA for re reminding my brother’s girlfriend that I own half of the house we live in so she can’t easily get rid of me?"

    I'm 15F and have been living with my big brother (25) for the last 3 years. Our dad d d 3 years ago and our mum abandoned us 7 years ago and is living abroad in Japan with her new family. I'm very independent and don't need a lot of attention and generally mind my own business. So I'm not a nuisance or a third wheel, I just need to be left alone. The house we live in belonged to our dad and he left it equally to both of us.

    My brother's been saying his girlfriend for a couple of years now, she's not bad and I generally liked her. However, she wants to move in here and they're talking about getting serious. I talked to my brother about how this would work and he thinks it's too soon to discuss it and we'll sort out the details when it's more serious.

    Ok so the other day she came to me and asked about my plans about uni and if I wanted to stay around and told her that yeah I plan to stay home while going to uni. She suggested it might be good for my "growth" to go to a different city and get exposed to new experiences and people, also suggested boarding school for next year. I smelled bs so told her what it's. really about and she mentioned that they're getting serious and want to start a family soon and I won't have a place here as they're g

    I asked why is she trying to get rid of me, I've done her no harm and she said it isn't personal and it's just that their family will deserve to have their own space without relatives living with them. I reminded her that I own half of this "space" so she's delusional if she thinks she can just get rid of me. She initially said my brother has done enough for me already and it's fine I do something for him but also said let's not continue this discussion now.

    Later my brother told me I was unnecessarily aggressive and instead. should have come to him about what she said. I told him I didn't approach her she was trying to manipulate me to get rid of me. He thinks she was wrong to do that but I was unnecessarily aggressive and she didn't mean bad and now I've damaged our relationship maybe permanently. Later he had a fight with her. He hasn't talked to me since then (4 days now), she also hasn't been over since then. AITA for being too aggressive to he

    kindaright-ish • 9h ago NTA . All these things she was suggesting, like boarding school, who would be paying for that? Your inheritance? Brother? Cos it doesn't sound like it would be her covering any costs. It's yours and your brothers house. Even if she did move in, it would still be yours and your brothers house. She would just be living there.

    I'd have been a lot more blunt if someone had the audacity to tell me to move out because they felt entitled to my inheritance and what I should be doing with it. Imo, the fact she hasn't been over and they haven't spoken is probably because she doubled down on what she said to you.

    • andthen... 10h ago Edited 7h ago • No, she cares about herself and her goals. You have legal rights to this home and if it's so important to them they can buy you out of it when they're ready, if you want to sell. ETA: obviously once you're of legal age to make that decision.

    FormSuccessful1122 10h ago NTA Isn't your brother also your legal guardian? Would she attempt to get rid of his child if he had one? You are currently a package deal and she needs to get over it. You can be as aggressive as you want when someone who doesn't even live with you is attempting to remove you from your own home for their convenience.

    Intro-Nimbus • 9h ago NTA If your brother thinks you should have come to him, it's worth mentioning that she came to you, and perhaps should have gone to him first. And it's not wrong to remind her that you would not be living there with them, she'd be living there with you.
