17-year-old tells mother that he doesn't like his 17-year-old stepsister or consider her to be family, parents retaliate: 'I accept her presence, but never felt close to her and never bonded with her'

We can't choose our family—or so we're often told. The reality is that we can't choose the family that we're born with, but we can choose the people that we consider to be our family thereafter. Family is who you find along the twisting path of life, and while there are those we might find along the beaten path, there are relationships we form that go on to mean more to us than we could have ever anticipated. The foremost of these people is our spouse, who at some point was a complete stranger to us but whom we have grown closer to than we could have ever realized. 

But, there's no telling where a relationship might lead from the outset, romantic or otherwise. Someone simply being in your life doesn't mean that they'll become close to you; in fact, often quite the opposite. This often becomes a challenge within blended families where the complex dynamics and layers of feelings at work often don't align with the expectations of the two people, the parents, who have chosen to be with one another. Those difficult pressures combined with close proximity to verifiable strangers may just lead you to feel worse rather than better about them. That's certainly the way it was for these stepsiblings, and the 17-year-old's admission to his mother about how he really felt about his sister caused a marked change and significant discomfort in the family.

    "AITA for putting my mom in an awkward position by telling her I don't like my stepsister?"

    My mom got remarried when I (17m) was 12 and that was 3 years after my dad d d. Her husband Jonathan has a daughter "Cassie" who's the same age as me. I met Cassie for the first time like 4 months before my mom and Jonathan got married. Cassie and I got along okay when we first met but I never warmed up to her and I don't really like her. She always wants me to

    do stuff for her and when I do she's fine, though she never says thanks, but when I don't she gets mad. She's short and I'm tall so she'll ask me to grab stuff that stored too high for her to reach. Or she'll ask me to move stuff around in her room when she decides to change the layout. Other times it's her asking me to explain an assignment we both have for school or

    telling me I need to explain it to her friends or something. And like I say she gets mad when I say no. It doesn't matter why I say no, like I'm doing something (my own assignment) but she has slammed doors, asked me why I'm so difficult in a frustrated way, she's tried to drag me and make me help her or her friends.

    The other thing is she finds it morbid that I talk about my dad and have a photo of him in my room. She came into my room one time and told me I should put it away and we argued because I told her not to touch it and she got offended and asked why she was so bad that she couldn't even touch the photo. But her attitude made me think she might try to hide it or worse. And she has told me before it's morbid to wish a de d guy SO happy birthday when I post stuff like that about dad.

    Her mom was never in her life. She's alive but didn't want to be a mom and I get that we have different experiences and feelings because of that but it frustrates me that she's got her own experience and can't try to be understanding. Then she calls me her brother but she talks to me that way.

    j I mostly just accept that Cassie's there and a part of my mom's life now and that she cares about Cassie. But I don't. I don't love Cassie or like her or care about her and I don't call her my sister. I try not to be so obvious or a about it and it's worked because I think Cassie thinks I care about her and my mom did but now I opened up to my mom.

    Jonathan doesn't really like Cassie going to parties with just her friends so my mom has always asked me to go. when she does so Jonathan feels better about it. I have resisted a few times and my mom encouraged me to do it even if it didn't sound like fun and I give in because I love my mom. But Cassie wanted to go with her friends and one of her friends' parents to a cabin next month. Jonathan wasn't sure and Cassie said I could come to make her feel better. He liked the idea. Mom was on board.

    I asked mom if we could talk just us so she brought me for milkshakes and asked me what was up. And I told her I didn't want to go with Cassie and her friends and I told mom I already did stuff for Cassie but it was incredibly forced on my part and I didn't want to be away from all my friends with her and her friends for a week. Mom said she thought we were close and I said I do my best to treat Cassie nicely but I

    don't actually like Cassie and I never have. Mom asked me what that meant and I described it more. I said I accept her presence but never felt close to her and never bonded with her and that I never really felt like protecting her or like she was my family. We talked for like two hours and then my mom told me I put her in a really awkward position because Cassie clearly doesn't feel the same even if she's not always the best at showing it. She told me Jonathan believed we were close too and he w

    My mom talked to Jonathan and said she didn't think it was a good idea for me to go on the trip. They fought about that decision and my mom has been a bit off with me since. Now I'm wondering if I should have just and kept it to myself shut the f and let it become obvious once we both went to college and I didn't make an effort to maintain a relationship with Cassie. AITA?

    Cute-P... NTA You were just being honest. You are under no obligation to babysit someone your own age AND her friends. It's telling that your mom never actually talked to you about upending your day to day life.

    Square... You are not Cassies emotional support animal or bodyguard. Her disrespect for you and your late father is beyond intolerable and your mother making this about herself is idiotic Your mother chose Jonathan and Cassie for herself, not for you. She has turned a blind eye on her stepdaughter and her sh behavior for 5 years and pretended to be oblivious to her tantrums and door slamming and constant invasion of your privacy. That's a HER problem.

    You are a 17 year old HS senior with your own friends and life. Jonathan isn't your father, he is your mother's husband. You are accommodating, respectful and civil to both of them and that's all you need to be and do. You are not his Co Parent or babysitting service for his 17 year old daughter either. You need to focus on your life, school, grades, friends and path to college.

    Hopefully your mother has saved the money from any life insurance your father had for your college and isn't using it to fund her life with her new husband and daughter along with any SS Survivor benefits she is collecting on your behalf. Focus on the road to college where you won't have to deal with Jonathan and his daughter

    ParticularBrush8162 NTA, you're not Cassie's servant, you're her step-brother. Her entitlement to your time and doing things for her is her problem. And it's your mother's fault for not testing what the relationship would be like before getting married. At least your mother's on your side, which is good.

    FionaFeeds You weren't cruel, you were honest and respectful about your limits. Your mom's just uncomfortable because now she can't pretend everything's fine.

    Blonde2468 NTA for one thing, you should have never been put in the position of being Cassie's 'guardian' for when she wants to go places. Second, EVERYONE would hold you accountable if you went and she did something and that's just not fair to you. THEY are the adults and THEY are the ones who should be looking out for her, not you! I'm glad you talked to your mother because she needed to know how Cassie treats you and that THEY need to step up and be her parents and stop expecting you to do it

    Kd-2330 21h ago • NTA- getting things from a top shelf...that's normal to do for anyone. Staying for a week with her friends, not so much especially if you don't really like her. Yes you put your mom in a difficult position but she did the same to you. Open communication is so important even if causes discomfort.
