AITA for telling my sister it’s her own fault she’s alienated from the family?

Five years ago, a simple request from an older sister to take a genealogy test set off a chain of events that would quietly fracture a once close-knit family. What began as a curious dive into their roots soon morphed into an unsettling silence, as the sister withdrew emotionally and physically, leaving her siblings and parents grappling with confusion and heartbreak.

As she moved miles away and severed ties with their mother, the siblings found themselves stranded in a web of unanswered questions and painful distance. The family’s bonds, once strong and unbreakable, began to unravel in the shadow of silence, leaving a poignant void where connection and understanding used to reside.

AITA for telling my sister it's her own fault she's alienated from the family?

I am one of three siblings: 29F, 27F (me), and 22M.

This all started about five years ago, when my older sister came to me and told me she was looking into our genealogy and wanted me to do one of those novelty genetics tests. I wasn’t enthusiastic about it, but she was weirdly insistent, so I gave her the samples she asked for and moved on, not really giving it much more thought.

At no point did I have a digital login for any results. I also never thought to mention this to my parents.

A few months after this, Sister moved six hours away for another job and was noncommunicative. She would call Dad every once in a while, but Brother and I found that if we didn’t call/text her first, we wouldn’t hear from her, and she basically cut Mom off outright.

When questioned about this, she would refuse to acknowledge that’s what she was doing. Ultimately, we all just accepted it. Mom was totally baffled and broken hearted, and the rest of us naturally became less close with Sister as a result.

Even she and Dad only talk a few times a year now, and none of us have seen her in person in five years.

Earlier this year, Brother did 23AndMe and got weird results that led to hard conversations. Mom and Dad came clean that the three of us were donor conceived, a choice they made because Dad is infertile.

They apologized for not telling us earlier, but Dad felt strongly about not telling us because he never wanted us to think of him as any less our dad.

Dad called Sister and told her this too after we talked, and she basically had a breakdown on the phone. It turns out that she knew Dad wasn’t her bio father, and firmly believed for five years that Mom had cheated on Dad and had been nursing intense resentments as a result.

Apparently she did a genetics test five years ago and was puzzled that the ancestry info didn’t match with what we knew about Dad’s family. That’s when she came to me to get a sample.

She sent it to a lab with hers, and they confirmed the results were genetic half-siblings, with the same mother and different fathers. She drew her own conclusions from there (that dad was my bio-father and not hers, and that Mom had had an affair) and uprooted her life to get a fresh start.

She’s now furious about the situation and feels like she’s been robbed of the last five years. When we last talked, I was maybe less sympathetic than I should have been and told her cutting us off with no explanation was an insane move, and if she’d told us even a fraction of what was going on, it could have been cleared up years ago.

I acknowledged Mom and Dad messed up here by not being truthful about our genetic identities (which I’m also struggling with my own feelings on), but in the end, it was her decision to do this dramatic move and slow fade with zero explanation.

I also expressed how hurt Brother and I had been to be left out of her life, and that it wasn’t fair to punish us for what she thought had happened. AITA?

Here’s how people reacted:

NTA, I understand why she’d be upset and why she’d come to the conclusion that your mother cheated, but even believing that why would she cut off contact with her siblings, lose contact with her dad? She made those choices herself, she could’ve confronted your mom and found out the truth five years ago, instead she decided to slowly cut off contact with her entire family? For five years? That just seems incredibly irrational to me.

Your parents could (and maybe should) have told you all a lot sooner, sure, although I understand why they didn’t, your dad is your father and those donors are just that, donors.

Feels strange to me though that you never questioned your sister asking you for samples and never giving you results, especially due to the timing of her becoming distant and moving/losing contact, but I guess it wasn’t your responsibility to figure that out.

She can be upset about losing 5 years with her family that’s fair, but you all lost those 5 years with your sister/daughter too.

I have no judgement but I actually respect your sister.

In her reality, she basically found a secret that could break apart her family and possibly uproot her little siblings’ and dad’s life, so she keeps it her burden to bear instead of troubling others, distances herself from the perpetrator (aka mom) without being absolutely mean to her. This took a lot of strength to do.

Even if she was wrong at the end, you should be appreciative of her. Be a good sister and soothe her. She thought she was doing what was best for her family aka you.

She is not an asshole in the slightest. But you will be if you or anyone in your family makes her feel worse.

Turn this situation as a team in a way that you’ll look back on and laugh in a decade, and not as a situation that further drives you away.

Everyone should apologise to everyone here. Especially your parents, cause again, the right intentions went horribly wrong.

LetMeFixDat4u

NAH but at least one dumbass.

I want to list what happened here:

* OMG, my dad is not my bio-dad.
* OMG, my sister and I have different bio-dads.
* That’s it, I’m not talking to anyone in the family.
* I don’t talk to anyone in the family for 5 years.
* My sister and brother do their own testing. Dad is not their bio-dad.
* Bro and Sis have conversations, and find out donor sperm was used for all.
* I’m mad that I put everyone, including myself, through help for 5 years for nothing.

If you refuse to communicate to people who are your family, what chance do you have in the world of having any close relationships. People today confuse data and information–your dad not being your bio-dad is data, your parents using donor sperm because of fertility issues is information. Don’t make decisions until you have information not just data. And for Christ sakes talk to people you call family.

AndSoItGoes24

You cut her off after finding out she was heartbroken because ALL of you had basically been lied to?

Your parents had their reasons for keeping the secret. But, the secret itself destroyed your sister’s faith in her family.

I can’t see me being upset with my sister for filling in the blanks with incorrect information after we’d all been lied to. All I see is someone who made a mistake because lies manipulated everyone.

At any rate, NAH. (If my father wasn’t actually my biological father, I’d prefer not to know, frankly. I identify as his daughter and it would be devastating to find out my truth is a big lie. Just sayin’, I feel sorry for your sister – not angry with her.)

NTA

I understand your sister’s reaction, but she took it all that way on a misunderstanding.

Your parents should have made this known to all of you from the start. These days of easy DNA testing mean that these secrets are usually going to come out, and often badly.

I was adopted, and knew from as early as I can remember. I’m glad I did. I’d hate to find out I’d been lied to for decades.

People should just be honest up front about this. Society puts so much emphasis on “bloodlines”, and people think that is the end-all of being “related”. Your parents are those who raised you, regardless of where the genes are from.

Odd_Fellow_2112

Your parents messed up this one. This is all on them. Your sister could have blown it wide open, and what if it was affairs? Then, the whole family would be a mess. Your sister, being the oldest, honestly puts you, your brother, and your dad ahead of her own mental health for this one. The fact that you don’t aee it this way baffles me and makes me feel even worse for her as you do not understand the trauma this can have on a person. She knew if she kept around, yall, she could never keep it quiet, and she would always be miserable around your mom and dad.
apology_for_idlers

NAH. This is all your parents’ fault. Once DNA tests were at Target and being marketed as stocking stuffers, they should have known this was not a viable plan.

To your sister, she was trapped in an impossible situation and didn’t know what to do. Avoiding everyone let her put off blowing up the family and maybe losing her dad forever, or actively deceiving everyone. There are definitely families where the father has cut kids out after learning about paternity fraud….she must have been so scared of being rejected in that way.

Enough-Process9773

NAH. Your sister thought she was the result of her mother having an affair and never telling anyone – she moved away and cut ties to avoid creating a family break-up. You are upset because you lost your sister for five years and your parents used a sperm donor to conceive you. Your parents, back when you were conceived, thought they were keeping quiet about it for the best – many heterosexual couples did just that, for years. Family therapy seems indicated. But no one was acting with malice or il-will.
Nobdes

Lol NTA by a mile.

You just wanted to comprehend what was going on while your sister was being shady.

She also made that assumption that your mom cheated and, while I’m sure your dad is a respectable guy, it probably left your mom heartbroken to just feel cut off from her own kid like that.

You didn’t even do anything that bad as a follow up, you just stated that it hurt you and your brother.

You’re a good person, just looking out for those around you. Keep being that good person.

VariousTry4624

Mild YTA. Yes your sister reacted strongly, but it is not her fault that your parents failed to be honest with all of you kids about their genetic parentage. You sister made a perfectly reasonable assumption about the information she was given by the genetic tests. If you had checked your test results (not that you should have) you all might have gotten the truth 5 years ago. If she needs to continue to be angry with your folks, that’s between her and them, not you.
JoshuaTreeJewelryco

Yes, you are the sort of the asshole for telling her that it is her own fault…

come on, this is your parents 100%, she was probably dying inside… What the actual ______?!!!? And she was nice enough to not disrupt the whole family dynamic and just excused herself because… mental breakdown existential crisis best to just process things in your own. Imagine finding out your reality is not what you think…

CarterPFly

NTA.another AITA that could have been resolved by a single, relatively short conversation.

Your brother did exactly what your sister SHOULD have done and now she’s probably very upset because she realises how epically fucking stupid her decisions were. No doubt she’ll project some of that embarrassment on others and lash out, as is the way when people get owned as badly as this.

Unable-Food7531

ESH.

You and your brother most likely weren’t “punished”. That seems more like an attempt of protecting herself from possible rejection by doing the rejecting first.

You are right to be unimpressed by her behaviour, but have a little empathy for how other people deal with traumatic reveals.

Few_Ad_5752

There are NAH. There has been hurt and there has been confusion. Time has passed and everyone has suffered. But now it’s time to put everything into perspective, to forgive and understand each other, and to love one another as you all clearly do.
HeliosOh

NAH

Your sister didn’t want to destroy your family. So she moved and reduced contact. By not confirming the info with either parent, she could justify not saying anything.

Of course, being abruptly cut from someone’s life, hurts.

Julia-t-theripist

NAH. Your sister probably didn’t want to ruin your family and tried to cut herself off in fear of heartbreak, while you missed your sister and got mad. Your family should have a talk with your sister and catch her up.
Pepper_Pfieffer

Your parents should have told all of you. DNA tests are so common now that only willful blindness could have led to this.

Did you ever mention the DNA test to either parent?

Your parents are both the AH’s here.

> She’s now furious about the situation and feels like she was robbed of the last five years

Um, well…totally on her. She can be mad at herself all she wants, but at no one else.

faayth

NTA. You’re right. Your parents suck on multiple levels, but if your sister had actually spoken to either of them five years ago, a lot of pain could have been avoided.

Conclusion

The original poster (OP) is dealing with complex emotions stemming from the revelation that they and their siblings are donor-conceived, a truth previously hidden by their parents. The central conflict arises because the older sister, having discovered this information years earlier through independent testing and misinterpreted results, chose to silently distance herself from the entire family without explanation, leading to significant emotional damage and resentment among the siblings.

Given the sister’s decision to self-isolate based on incomplete and incorrect assumptions, was the OP justified in confronting her about the damage done by her actions, or should the OP have approached the situation with more patience given the sister’s five-year period of private suffering and misunderstanding?
