AIBU to end things with my sister-in-law after years of helping?

Fedup0707 · 11/08/2026 20:26

need some honest opinions because I'm very angry and upset and don't know if I'm seeing this clearly.
She's my SIL (my brother's wife). I've never particularly liked her, but she's family and for 17 years I've always tried to be there for her. I look after her children, send my own children to help her and whenever she needs something I tend to run over. I've always felt you support family, even when you don't particularly get on.
However, I feel she constantly blames others, twists situations and portrays herself as the victim. She has a very difficult relationship with my brother and, although he's certainly not blameless, I feel she takes their problems out on the wider family. She's also accused my mum of causing problems between them.
Recently there was an argument over a duvet cover. My brother wanted one, so I gave him one of hers. I accept I should have asked her first. She rang me furious, shouting "how dare you" and accusing me of causing trouble between her and my brother. We both shouted at each other on the phone and I told her i knew that her and her brother had conspired and tried to separate me and my husband, because she wasnt happy being married to my brother. (They are still married) mainly for the kids.
I messaged her afterwards because I was fed up with being blamed and accused when I feel I've done so much to help her and her children. I told her I wouldn't get involved in her affairs again.
Then today my mum came out of hospital. My SIL was there, and I felt she was being fake sympathetic towards my mum as shes previouslybeen awful to her but trying to show look I'm good etc.
I was still angry and confronted her. I told her I didn't think she was a good person and that she should apologise for things she'd said previously.
She told me "don't talk to me." listening to your voice gives me a headache and i said dont talk to you "forever?" And she said well im not a good person and I said I agree your not and she replied "don't talk to me ever, our relationship is finished."
I know I started today's argument and I'm not denying that. I was angry and deliberately confronted her rather than walking away.
But I feel I've spent 17 years helping her, looking after her children and running whenever she needs something, while she repeatedly blames me, my mum or my brother when things go wrong.
I've also realised I've probably pretended we're much closer than we actually are because she's family.

Nobody said that @Fedup0707. I’m genuinely sorry you are having a rough day but please don’t start on the people who are trying to help you.

You put a post on AIBU, which isn’t known for its nuance, and you were desperately unclear (prob because you were upset). The advice you’ve had is really solid - you are overthinking, let it go, find something else to do to stop it feeling so overwhelming.

Nobody has said that they don’t fight with their families and never argue.

In fairness many posters are not strictly trying to help. ....

Ignoring the spam, you sound way too involved with your brother and SIL life OP.

user1492757084 · 12/08/2026 00:49

Back off from your brother's family.
Learn to smile politely at essential family gatherings.
Cease saying anything offensive about her.
Take it one week at a time.

Reward yourself by findong a new bunch of unconnected friends.

If we could move we would, but not as easy as that, am main carer for my parents, who are needing more and more help now, plus work and being able to afford to move. Its just not possible, have thought about it alot but just cant at the moment, I know my tolerance at the min is at an all time low i think cause of going through menopause, i shouldn't have argued today or brought it up, should have walked away, but still felt really angry and I normally don't care, as know she has form and try to ignore, but i didnt.

You don’t have to move miles away but some distance so you aren’t in each others pockets might be good. I know it’s not that easy though

WhatNoRaisins · 12/08/2026 06:30

I don't get why you're so enmeshed with and have given so much support to someone you don't like. That was inevitably going to lead to resentment and it sounds like this has made you behave really badly here. You need to be polite but distant and be discerning about what you share with her.

Helgirl666 · 12/08/2026 08:22

Frankly I would have done the same. Your only human ans can take only so much! Sounds like you are well rid of her. Don't help out again and let her sink or swim on her own I say. One less toxic person in ur life - well done you!

It’s the classic people-pleaser thing of running around for years offering services to someone you don’t like, all the while seething with resentment, and then cracking when it’s clear your 17 years of service didn’t get you what you thought they were getting you. You see it an awful lot on Mn. The answer is obviously not to give more than you’re able, ever, and not to do things for years for someone you dislike when you don’t want to.

SunnyRedSnail · 12/08/2026 08:42

You and your SIL sound very similar and both enjoy making a mountain out of a molehill.

Sounds like you clash as you are so similar.

Eurovisionwatcherbecauselol · 12/08/2026 12:52

Firstly I don't understand how people don't understand the duvet post? It was messaged in simple terms so Where's the confusion?

But secondly I don't understand how it all blew up from a row over duvets as it wasn't your row it was between bro and sil?

Thirdly (and you knew this) you were wrong to both act like children in front of your mother!

So forthly from now on just step back but try and be civil keep communication between you and brother but if sil about be short but polite!

LouiseK93 · 12/08/2026 17:53

I think its probably tip of the iceberg sort of thing

Doubledenim305 · 12/08/2026 18:18

Just don't waste your time helping her any more. Just silent silent silent.
You sound like you have just realised she's awful and are pained at all the effort you made in the past. That's why you are smarting.
It is what it is.
Let them do their thing and don't offer anymore help.

HerbertPootle · 12/08/2026 18:22

I think your brother is at fault here. He could have phoned his 13 year old daughter to bring a duvet cover out to him as he left. Why ask you? Sounds like they all treat you like a slave. Leave them to it, they’re adults.

Millerhouse1 · 12/08/2026 18:24

In families an entitled person can argue over anything, hers was a duvet. Whether you were right or wrong an argumentative person will always find fault. Forget her and move on, rid yourself and your children of being used by her. There's always one in a family, and yours is her.

Iamgettingolderandgrumpier · 12/08/2026 18:27

Sorry, you’ve spent 17 yrs putting up with this cr*p. Sounds as if you quite enjoy the drama. If you really don’t, just go no contact. You can still see your brother. He can meet at yours, your mums or neutral ground. Avoid the cow!

winter8090 · 12/08/2026 18:36

The problem is if you cut her off it will
impact the relationship with your brother and his children.
id find a middle ground. Be pleasant but distance yourself a bit in attempt to stop getting involved in their dramas.
The duvet situation was clearly a misunderstanding and I’d just say you did you best to try and help and leave it at that.

MoonWoman69 · 12/08/2026 18:37

In a word, pathetic.

ChocoChocoLatte · 12/08/2026 19:12

Jesus wept are you all 14. Stay the hell away from each other. She sounds like an absolute melter and you need to learn not to people please.

Vaxtable · 12/08/2026 19:21

Just let it go. D9 t bother speaking to her again and let her do her own thing

greenpolkadot55 · 12/08/2026 19:29

NotAnotherScarf · 11/08/2026 20:43

No me neither

I'm not following it either. i thought it was the mums duvet cover..did you give it to her while your mum was in hospital ?

HereWeGo1234 · 12/08/2026 19:30

Have you heard of greying or grey rock method? Google it if you haven’t - it might help you in your dealings with her in the future.

maxslice · 12/08/2026 19:34

You gave away something that didn’t belong to you. You try to minimize it, but it was just wrong. You may hate her for other reasons, but if she gave away something that belonged to you, you’d be on here ranting about that. You are being unreasonable.

Gengha · 11/08/2026 22:07

So did your SIL then go to the Air BNB to retrieve the duvet cover?

where was the air bnb?

Should the Airbnb have duvets in covers for the guests?

Bababear987 · 11/08/2026 22:20

Stop living in each other's pockets and get a hobby... I'd suggest reading.

And exercise to burn off that rage.

BeUmberMember · 12/08/2026 20:15

The duvet cover issue sounds like a storm in a tea cup, but some people are precious with their things and she may only have a couple, one on the bed and one in the wash. We cannot choose our family members and obviously you have been supportive to your brother and his family for many years, and I am sure he appreciates it, even if she doesn't. You only have one family and obviously have to consider your mum's feelings if you were to stop speaking to your sister in law, plus your brother's, so for the sake of restoring family harmony I would just let this go, in the knowledge that your sister in law will need you in the future and not want to continue not speaking. You as the more mature adult can back down in the best interests of all your family.
