AITA for telling my mom I’m not an aunt and not going to pretend just for her?

From the moment their lives intertwined, the bond between the two stepsisters was anything but sisterly. Beneath the surface of blended family photos and shared spaces lay a tempest of resentment and cruelty, where shattered memories and stolen moments became the currency of everyday life. The younger sister’s rage, born from her fractured past and turbulent custody battles, erupted in acts of destruction that tore at the fragile threads holding their family together.

Every broken picture and broken trust carved deeper wounds, turning childhood innocence into a battlefield. The quiet suffering of the narrator, marked by humiliation and loss, revealed a haunting truth: some scars are invisible but no less painful. Their story is a raw testament to the enduring pain of fractured families and the desperate hope for peace amidst chaos.

AITA for telling my mom I'm not an aunt and not going to pretend just for her?

My mom married my stepdad when I (20f) was 7 and my stepsister was 6. She was such a nightmare to deal with and it only got worse after her dad took custody of her from her mom when she was 13.

She smashed up the collection of photos my mom had of my uncle/her brother who died when they were kids and she made sure those photos could not be salvaged. She broke something valuable that her grandma (my stepdad’s mom) owned.

She would spit in my pillow so I couldn’t sleep on it. She would tell me to give her stuff. So when I got a phone she demanded it. If I was eating a chocolate bar she demanded it. Her dad at one point had her in therapy x3 a week and he would punish the hell out of her for stuff like spitting and breaking shit.

One time when we were 15 and 16 we both got in trouble because she tore the photo I had in my bedroom of my dad and grandparents and she smudged food stains all over the fragments left and I lost it.

I told her she “fucking sucked” and I was so glad she was not my real sister because I would never want to be family with someone as unlovable as her. I told her I never disliked anyone as much and my life was so much better without her in it.

After that things were very different. My mom said she understood that I was upset but that I should never say such cruel things to someone. She encouraged me to apologize and say I hadn’t meant those things.

But I had. My stepdad and I had gotten along okay up to that point but me saying his daughter was unlovable and that I wished she had never been in my life was a step too much for him which I get.

We pretty much co-existed after that. For me things were just never good to begin with.

Now I live pretty far from my mom. My stepsister recently moved back in with them after she had a baby and my mom has tried to convince me that this is the perfect time to put the past in the past and move forward.

My mom has brought up my being an aunt many times before. My stepsister sent me a video via my mom’s FB saying that she had forgiven me for what I said and was ready to move forward.

I got pretty tired of my mom trying and calling me an aunt so I told her I wasn’t an aunt. I told her I have no siblings and so I can’t be an aunt. She told me it was childish to say that when everybody else is ready to move on from all that.

I told her I was not. That I had never grown to care about stepsister and did not want to be in her life, or to have her in mine, and her child was an extension of that. She’s mad at me for saying that and my stubborn stance.

Here’s how people reacted:

Ok great, she has forgiven you and is ready to move forward. But rightfully so, you haven’t forgiven her for her atrocious, and extremely hurtful and permanent, behaviours. And you are not ready to move forward with a relationship. You are absolutely entitled to that. And then to top it off it sounds like she hasn’t even attempted to make amends for her side of things

I rarely suggest going no contact with people. But if your mom refuses to understand that you deserve respect and understanding. I would definitely encourage you to go no contact, at least for a little while

sinking-fast

NTA. If she wants to make amends with you so badly tell her she can start by taking accountability for all the shitty things she’s done. My guess is that she hopes you fall in love with her kid so she can use you as a free caregiver, exploit expensive gifts from you, etc. This person TRAUMATIZED you and ruined a large part of your childhood. You don’t have to forgive your abuser. The fact that your mom didn’t protect you from your step sister’s abuse is unconscionable. I’d kick any partner to the curb if their kid was abusive to my kid. That’s a fucking deal breaker.

MasterHarperJamieJo

no, you are not, but you are holding onto the anger and it’s hurting you rather than her. as for her child, yes. you ARE her aunt. and she had NOTHING to do with the mess her mother made. you don’t have to love the child, just don’t hold her mothers’ problems against her. as for your step-sister, she forgave you? she has no place or right to forgive you, she needs to be apologizing to you and your mother for everything she did. I would suggest you sit down with your mother and explain your stance, but really, you ARE an aunt. that’s just being childish.

Your stepsister forgave you for what? You telling her the truth? After all she did what you gave her was far lesser than what she deserved. If I had been in your seat growing up I’d resent that person for the rest of my life and never want to have contact with them ever again. NTA, she hasn’t changed and I’d go low/no contact with my mom if she continued to bring it up although that’s just my opinion on the matter, so whatever you feel is right.

ApartLocksmith1

NTA. It’s nice to be able to forgive and forget these things but sometimes too much damage has been done and it’s impossible to get past the hurt.

You accepted that you will never have a relationship with your stepsister years ago, it’s time for everyone else to do the same.

If you can get to a stage of indifferent tolerance (whereby you can be in the same place for the holidays), I’d say that’s as much as anyone has the right to ask of you.

Consistent-Leopard71

NTA at all. Your stepfather and stepsister were you mother’s choice, not yours. Your mother has tried for 13 years to get you to play happy family with a stepsister who was an abusive bully and you understandably refused. I’m sure your mother and stepfamily would like to “move on”, but no one has offered you an apology, which all them of owe you. You do what you feel is best for you. Good luck!!!!

EDIT: wording

everydayimcuddalin

NTA…one day you might feel ready to let bygones be bygones but until that time they can’t force you, your feelings are valid.

I also don’t like that stepsister forgave you but didn’t own her sh!t and apologise…she sounds like the same narcissistic AH who hurt you on the reg growing up.

NTA, but everyone else is. Especially your mother and stepfather who did nothing to stop your stepsisters cruel behaviour, especially after she ruined precious photos of the deceased. Why on earth did they let her get away with so much?

[deleted]

> because she sent me a video via my mom’s FB saying that she had forgiven me for what I said and was ready to move forward.

This implies you said something that you needed to be forgiven for. If anything, you were too kind to her.

DubiousPeoplePleaser

Wait, what? SHE had forgiven YOU?! She bullied you for years and she had the audacity to say that. Sorry, but she needs to apologize for every thing she did and acknowledge her fault in this. You are so NTA.

lemoncake206

NTA – you have no obligation to include your stepsister in your life. You never had a familial relationship with her, so she’s not family, especially if she never apologized for everything she did to you.

>she had forgiven me for what I said and was ready to move forward

Hmmm.

Ask them all if she (stepsister) is ready to properly apologise for her behaviour.

NTA

Borgteddy

So she has forgiven you for the things you said to her, but where is the apology for all the things she said and did to you?
Definitely NTA.

jcqrze

NTA.

If she’s ready to move forward, she can start by apologising (and even then you aren’t obligated to forgive her in the slightest).

atomic_winter

NTA. Regardless of blood relation or not, you have zero obligation to continue to force a relationship with someone toxic.

Conclusion

The original poster (OP) is maintaining a firm boundary against involving herself in the life of her stepsister, viewing the relationship as permanently damaged by years of significant mistreatment, including property destruction and personal harassment. This stance directly conflicts with her mother’s desire for reconciliation and the acceptance of her role as an aunt, creating tension within the immediate family structure.

Given the documented severity and persistence of the stepsister’s past behaviors versus the family’s strong push for forgiveness and moving on, is the OP justified in refusing all contact and acknowledgment of the new baby to protect her emotional well-being, or does the familial desire for peace and connection outweigh the OP’s need to enforce consequences for past actions?
