AITA for refusing to exclusively care for my disabled sister?

Tension hung like a storm cloud in the cramped family living room, where old wounds seemed to seep from the walls. A 55-year-old woman, her face etched with years of resentment, faced a heart-wrenching decision: refuse to care for her sister, now immobilized by a stroke. Their past was a tangle of betrayal—stolen savings, cruel taunts about a premature child, and unrelenting verbal barbs that left deep scars.

Now, with her sister’s mobility gone and her nephew’s pleas ringing in her ears, the woman stood at a crossroads. The weight of family duty pressed against her resolve to protect her own peace. This isn’t just a story of saying “no”—it’s a vivid portrait of a woman reclaiming her boundaries after decades of hurt, pulling readers into a messy, human struggle where loyalty and self-preservation collide.

‘AITA for refusing to exclusively care for my disabled sister?’

I (55f) have a sister (60f). She was perfectly healthy until last year after a stroke her legs completely stopped working. For background reference my sister and I never got along. When I entered uni in my early 20s she went behind my back and stole my savings and my parents defended her and backed her up saying she was in need of them because she had kids.

When my young daughter came out premature she would mock me for not being able to have healthy kids. Those are just few examples. Flash forward few years back, when her oldest son got married, his new wife got diagnosed with b**ast cancer.

My sister claimed her dil was lying about it and she proceeded to make that girls life a living hell by always trying to cause conflict between the couple and being entitled over seeing their kid when they had sued her for child n**lect one time while the kid was in her care and almost drowned because she was busy smoking.

As you can see her oldest son isn't getting along with her either and neither is her dil. Her younger son is out of the country and doesn't have much contact with anyone. Last year after her stroke her legs stopped working and she required special care.

For some time his son had hired a nurse to care for her but a couple of months ago the nurse quit due to the fact she was verbally abused by my sister. After that her son aka my nephew tries to tell me that I should care for her since they don't want that responsibility with his wife after all his mom has done to them.

I said I understand they don't want that responsibility but it's not my responsibility either and I've endured my part of verbal and emotional abuse by my sister. When I refused to help them out both my nephew

and his wife called me TA because I am being insensitive towards the fact that the wife has cancer and the fact they can't see her after what she did to their kid. I wish I could help but I don't feel like its right for that burden to fall on me considering I've suffered because of her too in a way. AITA?

This family drama cuts to the core of duty versus self-preservation. The 55-year-old woman’s refusal to care for her sister, wheelchair-bound after a stroke, stems from a lifetime of toxicity—stolen savings, mockery, and verbal abuse. Her nephew’s push to offload the responsibility reflects his own exhaustion from his mother’s behavior, yet it unfairly burdens the woman, who’s endured her own share of pain. Both sides carry legitimate grievances, but the sister’s unrepentant past tilts sympathy away from her.

Family estrangement, like this, is more common than many realize. A 2015 study in the Journal of Marriage and Family found that 12% of adults are estranged from a sibling, often due to unresolved betrayals or ongoing conflict. The woman’s firm boundary mirrors a growing trend of prioritizing mental health over obligatory family ties, especially when trust has been repeatedly broken.

Dr. Joshua Coleman, a psychologist specializing in family dynamics, observes, “Estrangement can be a necessary act of self-protection when relationships are consistently harmful”. This perspective validates the woman’s stance—she’s not obligated to endure further abuse, even from a disabled sibling. Her sister’s condition doesn’t erase decades of harm, and expecting otherwise risks perpetuating a cycle of pain. Coleman’s insight underscores the importance of setting limits, even when family is involved.

For resolution, professional caregiving or social services could ease the burden, as Reddit’s Senior-Term-635 suggested. The nephew might explore these options, or family therapy could address underlying tensions, though the sister’s behavior makes reconciliation unlikely. Encouraging open dialogue, while maintaining firm boundaries, offers a path forward.

Check out how the community responded:

The Reddit community weighed in with fiery conviction, their responses crackling like a campfire of candid takes. Most sided with the woman, declaring her free of obligation to a sister who’d spent years burning bridges. They saw her refusal as a stand for self-respect, not selfishness, emphasizing that her sister’s disability doesn’t erase a lifetime of cruelty. Commenters urged her to hold firm, some with a sharp wit that cut through the drama like a well-aimed dart.

From calls to block persistent guilt-trippers to suggestions of social services, the community’s opinions were a mix of empathy and pragmatism. They painted a clear picture: actions have consequences, and the sister’s toxic past left her with few allies. These views highlight a collective belief that personal boundaries trump familial duty when trust is shattered, offering a raw, unfiltered lens on the situation.

MissMurderpants − NTA I’d tell nephew that his mother pulled the same crap with you and she can kick rocks. If he brings it up again I’d block him.

Veridical_Perception − NTA. You have absolutely no obligation whatsoever to take care of your sister.. The nephew is trying to use guilt to manipulate you. By giving reasons or discussing it, you open the door to the idea that you can be convinced, that your position is negotiable, or that your reasons are wrong, so should be debated.

Simply say 'no' and stop discussing it with them. If they persist with trying to use guilt, simply tell them that they cannot shift their own guilt onto you to make themselves feel better about abandoning his own mother. Being sick or needing help doesn't suddenly make people decent human beings. There are consequences to a lifetime of bad behavior. Your sister is living those now.

DubbocredoKiev − NTA You don't owe your sister anything or her children. Just like they have valid reasons for not wanting to care for her so do you.

Senior-Term-635 − NTA. Nephew trying to force you to care for her is. I'd tell him you understand, but, if he refuses to care for her, you are simply going to call adult social services and let her go to the system because you can't care for her and she seemingly doesn't have the means to care for herself.. Ask if he's informed younger son about mom's care.

Stoat__King − NTA. She made her bed. Now she gets to lie in it. There is a certain symmetry to it.

bobledrew − NAH. Except for your sister. Your nephew must find some way to deal with his toxic mother. You have no obligation in that.

introverted_smallfry − NTA she burned all her bridges.

blacksteel15 − NTA. You're absolutely right. The fact that your sister has alienated her kids to the point that they're not willing to care for her and everyone else around her to the point that no one else wants to help doesn't make you obligated to do it instead.

They can decide whether they're okay with washing their hands of the situation and letting her work through the system and figure it out herself, but it's not okay to try to dump the responsibility on you to avoid having to make that decision.

noccie − NTA. If her mouth and hands are working she can look for the help she needs herself. Stand your ground and don't get involved in that mess.

10PointOne − NTA Your sister has been a textbook narcissistic abuser your whole lives and the rest of your family has enabled it. She's a grown ass adult who can figure it out herself. If the rest of your family wants to help, they can. If you want to throw some support financially, fine. But do it from a distance. Her becoming disabled doesn't entitle her to more opportunities to abuse you.

This tale of fractured family ties leaves us grappling with the messy balance of duty and self-preservation. The woman’s refusal to care for her toxic sister isn’t just a personal stand—it’s a bold claim to her own peace after years of hurt.
