AITA for not wanting to be best friends with my step-siblings/family?

Hi everyone, I (16F) am the youngest sibling of five half-brothers. I grew up very closely with three of said brothers and would occasionally see the other two when their mom would allow. Two of my brothers have moved out and it had only been I and my older brother (19M) still living in the house. My parents got divorced around seven years ago: my dad remarried in 2024 and my mom just recently. Neither of my parents can have any more children and my dad married a young woman with no kids. However, my mom remarried a guy with two kids (14F & 10M).

Naturally, this came as a surprise to me, as I’d gotten used to the state of my home life; but, I tried my best to come into this new situation with an open mind. When my mom remarried I honestly didn’t know too much about the guy or his kids and we’d only met a handful of times.
While I try to be cordial and say hello when circumstances arise, I never get the same energy back and it honestly feels desperate (?) on my end.

The kids never greet me and treat the house like a paradise whenever they’re over. All three of them are very inconsiderately picky eaters and we had a "Mac and Cheese Incident" where my stepsister ate an entire pot of macaroni, completely disregarding the entire FEAST my mom had just spent hours preparing for dinner (the macaroni of which, my mother prepared as a side for us to all SHARE)… My stepdad also doesn’t cook, clean, or do much of anything really. Now, I’m not saying he’s a bum, but he’s just really unhelpful around. I, my 19 y/o brother, and my mom are always washing the dishes; preparing the meals; or just generally caring for the house.

Additionally, my mom acts as though it is my fault that me and my stepsister don’t talk, but honestly we’re at two different maturity levels; and, while I’ll be in college next fall, she’ll be a sophomore in HS. Furthermore, we simply have two different personalities with me being more reserved and introverted and her more out-there and extroverted. Additionally, my mom says that my stepsister wants to make connection, but such desires aren’t ever expressed when we’re together: she goes onto her phone and I follow suit.

And now, to make matters worse, my mom acts as though I am always in the wrong for not initiating conversation with my step-family and never vice-versa. I’m content with us simply being polite without being besties, but my mom acts as though the relationship changes she makes in her life must also apply to mine.

I honestly don’t know what to do. I’ve always been the youngest and now I’m getting ready to leave the house, so this sudden change in family dynamics is just… Is it okay to just be friendly with my step-family without acting like they’re my actual family? Or AITA for not sacrificing my own comfort to make them feel "comfortable?"

  1. I’d also like to note that I don’t have a bad relationship with my dad or step-mom, I just only see them two weekends a month because of distance.

    1. Your mother needs to grow up. You’re not going to become close to these people you barely see and when you do, have to clean up after them. 

  2. It’s shocking that your mum married someone when you hardly knew him or his kids.
    And then to blame you when you didn’t all automatically become a “happy family” is absolutely insane. 

    None of this is your fault! You have done nothing wrong. 

    NTA 

  3. NTA ofc. Your mother has no control over your step siblings’ behavior but she thinks she can influence you, so that’s why everything is always ”your fault”. You can try to make her stop triangulating by saying ”if my step sister wants to hang out with me, she can tell me herself, you don’t have to act as a go-between.” You can also try just telling your mom that you are happy being polite and distant with her, and that a friendship might form later if you can get used to your new step siblings at your own pace without pressure. I honestly think if your mom keeps pushing you, you might end up disliking her purely because of the pressure.

  4. NTA- There’s only so much you can do, if your mom wanted you two to connect she would spend more time initiating opportunities for connection. Like a girls trip to get pizza, nails, walk around the neighborhood, etc.

  5. NTA but you try more.

    When you are in the room with your mom and the step sibling, initiate a conversation and genuinely try to keep it going for a couple minutes. Try that a couple times per visit. It is unlikely to work, but you will have given it a shot and all it will cost you is 2 minutes.

  6. Your mom is now starting to realise the dyanmic she has married into. 

    You are the one who is easier to manipulate because you are the one who is more complicit in doing things…ie. because you clean up after yourself you put more effort in therefore you have the effort to put in here too. You are also older.

    Your mom is probably having the same conversation with the sister…or saying wouldn’t it but nice to be friends…but it is nice for her.

    I’d just tell your mom that she isn’t interested you’re not interested and does she really want this to be her life when you move out…her cleaning up after everyone.

    I’d honestly start studying at the library or get a part time job to just not be at home as much. You’ve only got a year. Keep your head down. This dynamic is going to get very rocky very fast when the two kids who do clean up after themselves leave. 

  7. NTA

    This is not your future… it’s your mother’s. She’s reaping what she’s sowed.

    Your mother made a bad/impulsive choice in spouse and is just now realizing what a horrible reality it is.

    She made the choice to move him in despite knowing you didn’t really know each other or the dynamics. She’s afraid to be alone, so she’s shacked up with a dude without asking her family how they felt. She’s now a single mother to 5 kids (including him).

    She’s taking out her resentment and aggression towards you bc she can’t parent his kids (or him ). She made her bed, and now she has to lay in it.

    You need to stop trying so hard. Stop cleaning up after them. Don’t ” help.” Go to friends, library, coffee shop, or stay after school to spend your last school year focusing on yourself and your goals. Your adult life is about to start. Time to plan for your future and stop worrying about people who DON’T MATTER.

  8. NTA, you’re not an asshole in any way. Things will develop in the way they were meant to, naturally.

  9. Your mom remarried a guy with kids that you’d “only met a handful of times”?

    Well that says all I need to know on her part.

  10. NTA, your mother acts as if you’re problem because she has no control over the other side. 

    I’d pointblank ask her why this relationship is made out to be your problem when she chose to marry a guy who you hadnt met for more than couple times before and his children cant even greet you normally. This so called “problem” is her own doing.
