Who do you go to when you have totally reached rock bottom? Most people would probably say their family; that's sort of what they're for. While other animal species instinctually separate from their young when they've learned more or less how to take care of themselves, we humans stay bonded with our kin throughout our lives. We're social creatures, and we are biologically motivated to form empathetic communities to support each other. However, we also have emotions, opinions, and hang ups. We hold grudges, have boundaries, and don't always get along with people just because we are related – either biologically or socially. 

In our story today, a young woman is pressured to house her stepsister after she gets kicked out of her own apartment. They never got along as kids, and they've barely communicated as adults, so she naturally decides to protect her peace. Her sister might not be crashing at her place any time soon, but now our protagonist has to deal with endless guilt-tripping from everyone else.

    AITAH for refusing to let my stepsister move in after she got kicked out, even though my dad says I should "be the bigger person"?

    My dad remarried when I was 18, and his wife has a daughter, "Kayla" (25F). We were the same age, but couldn't be more different. She was always

    popular, always had friends and parties, and made it very clear I wasn't her "real" sister. She'd mock my clothes, my books, even my voice. I basically stayed out of her way.

  • If they're so worried about their daughter, why don't the parents just offer to take her in?

    Shoddy Move6054 NTA. Just because someone is technically family doesn't mean they get a free pass into your life. Your dad doesn't get to volunteer your home because he feels guilty about her. Good for you for having a spine.

    mistygigglybliss OP Thanks, that's exactly how I feel. I get that she's struggling, but that doesn't erase the years she treated

    me like crop. I worked hard for this space and I'm not giving it up just because my dad can't say no to her. I'm not her backup plan.

    ReactionEither6684 Honestly? If she moves in, she'll never leave. And you'll be footing the bill, picking up after her, and getting blamed when she blows up again. Hard pass. NTA X100.

  • It's great that she is setting her boundaries this early on. It's easier to deal with a bit of guilt-tripping than bankrolling a whole other person for who knows how long.

    mistygigglybliss OP That's exactly what I'm afraid of. Once she's in, there'll be excuses nonstop, no job yet, no money, "just

    a little longer." And somehow I'll end up the villain when I finally say enough. No thanks. I've worked too hard for peace just to hand it over.

    Dependent_Interest87 NTA. If your dad and her mom are so concerned they can have her stay with them or pay for her rent. You don't have a real relationship with her.
    via u/Dependent_Interest87

    Biggest proof of that is the fact that your dad called you to ask. She couldn't even bother to ask cuz she knew what the answer would be. Don't get guilted. You have done nothing wrong.
    via u/Dependent_Interest87
  • 24
    mistygigglybliss OP She didn't even ask me, she made my dad do it because she knew I'd say no. That alone shows the kind of relationship we have. I'm not being mean, I'm just not letting people take advantage of me.

    Debbie0357 You are not the AH tell your dad that his other daughter can live with him and his wife her MOM.. my gosh, you better stay strong. and protect your peace.!!

    because I worked hard and got my life in order. If they're not opening their door for her, that says more than anything. I'm not the AH for choosing peace over chaos.

    grayblue_grrl Nope. Your step sister is not your friend and she hasn't been family. Your dad can take her in. She's not your problem.

    mistygigglybliss OP She's never acted like family, so I'm not treating her like one now that it's convenient. My dad can play the hero if he wants, I'm out of it.
