AIBU to cut SIL out finally …

AIBU to just quietly cut SIL out of my life? (Used AI to help me write this up as it’s a long story!)
Just to say upfront, I’ve used AI to help me write this because there’s years of history and when I try to explain it myself I end up rambling 😂 But the events/opinions are mine.
DH has 3 brothers and 1 sister. His sister has always been difficult/selfish/competitive according to DH – those are his words, not just mine. They had a very privileged upbringing – private schools, amazing holidays, etc – but there has always seemed to be this underlying competitiveness between the siblings.
SIL is very close to MIL. They see each other pretty much every day and SIL talks constantly about her children/their achievements etc. We live nearby too, although barely see SIL.
There have been years of little incidents, but one from years ago has always stuck with me because it happened when I was incredibly vulnerable.
I had just given birth emergency c-section after failed induction - and became very ill. I was in hospital with an infection, had been back into surgery, and my newborn was in NICU being supported with his breathing. I was also about 300 miles away from my own family.
We also had a 3yo DS.
Because of infection/vulnerable babies, the midwife asked DH if possible not to bring our 3yo onto the ward/NICU that day. I believe a couple of babies had fallen ill.
DH therefore asked MIL if she could have our older DS so he could come to the hospital and be with our baby (and me to some extent but I was quite bed ridden and very poorly).
It happened to be SIL’s birthday.
MIL apparently told DH that SIL had said she didn’t want our DS there because it was her birthday and she wanted it to be just her mum and her own DS, who was also 3 at the time.
So DH couldn’t leave our 3yo with MIL and therefore couldn’t come and be with me and our newborn.
That has honestly never left me.
Fast forward about six weeks. Baby and I were finally home after a long hospital stay. I was post-C-section, recovering from infection and still couldn’t drive because of the complications.
I asked MIL whether, just one morning a week for the next TWO weeks, she could take older DS to preschool because I was really struggling physically.
SIL was there and said something along the lines of, “Other people can do it, why can’t you?”
I said because I’m poorly and physically struggling!
I then said fine, DH would have to do it, although it would affect his work. MIL’s response was that she’d speak to DH.
And this isn’t really about those two incidents anymore. There have been years of similar behaviour and I think I’ve reached the point where I simply don’t want a relationship with SIL.
I don’t want a big confrontation. I don’t want DH to stop seeing his sister. I wouldn’t stop the children having relationships with family either. I’m happy to be polite if we’re at the same family event.
I just don’t want her in my life beyond that.
Basically treating her as DH’s sister rather than someone I personally have a relationship with.
Im very close to my brother’s wife and my mum treats her like another daughter. It’s all very different in my family. 🙏🏽
Part of me wonders whether I’m holding onto things that happened a very long time ago. But another part of me thinks that how someone treats you when you’re at your absolute lowest tells you quite a lot.
So AIBU to just keep stepping right back and stop bothering? Or do I need to let the old stuff go?

Seems to me, it’s as much your MiL as your SiL.

But I do feel a bit for her position as the one girl in among 4 boys. Your DH says she was competitive- maybe she just had to work extra hard to keep up with the expectations of her in a family dominated by men?

Absolutely not at all… she comes first she rules the roost.

@SoBoredOfSelfDoubtHowToGetOut@SunshineAndFizz@Gotbackthank you! Thought I was going a bit mad… I guess they’re also local so the preschool was 8 mins drive from me and about 15 from them… fully retired - two car household. Really competent … lead in lots of church stuff, charity stuff - very involved in the community, very easy for them to do that.

I'm sorry you went through all that & your in-laws made it so much worse. And for what? An adult's birthday?! It's actually shocking that people can be so callous.

You're doing the right thing keeping them at bay. I don't think I'd ever be able to see or talk to them again.

Of course step back, you don’t like her, she doesn’t like you, so of course barely see her.

im sorry your baby was in nicu, but you seem to be using this to blame her and your mil, when what about all the other people you could have asked? Maybe some on my list aren’t an option for whatever reason but - your fil, his brothers, any of your family, any friends, a babysitter, a neighbour. If you really only have one person you can call on in an emergency, I’d say you need to widen your circle. And again, with the dropping off for nursery, surely that’s completely his father’s role? For 2 weeks, his job can cope.

you don’t like her, so you’re blaming her for things that aren’t her responsibility

Not read anything quite so stupid in a long time on MN.

What a ridiculous answer.

Why ask the grandma? Surely in most families this is the first person you’d ask in the circumstances.

And this spoil brat of a SIL doesn’t want her mum to help out her son and family in a time of need. Disgusting behaviour.

Are you honestly saying her reaction is okay? You wouldn’t jump to help your family out?

SunshineAndFizz · 12/08/2026 17:44

She’s disgusting.

muddyford · 12/08/2026 17:39

When my SIL was widowed (her husband was DH's brother)seven years ago I rang her every couple of weeks for a chat. DH died recently and she hasn't bothered to ring once and it won't be me picking up the 'phone.

Not at that time we didn’t have anyone we have more people now, don’t you think what they did was pretty shit? All they had to do was take DS with them for lunch with the other 3 year old …

MIL is so so so enmeshed it’s uncomfortable to see. And SIL really uses that control she has. Very sad. I think the news of my cousin’s baby’s birth has brought it all back plus my own trauma of being in hospital

OP posts:
Cherrysoup · 12/08/2026 12:08

Sounds like you don’t see her much anyway. Don’t push for her coming round, don’t facilitate any visits there, you’ll barely see her. Your mil sounds like she’s totally enmeshed,

What disgusting horrible advice, says alot about you.
There are far better ways to go about this without stopping to being foul mouthed.

Oh I don’t know.

Being foul mouthed is wonderfully effective sometimes. Not to mention cathartic.

I would far far rather be foul mouthed than someone who refuses to help a man whose wife and child are terribly ill in hospital.

SIL is a bitch and I would blank her personally. Or tell her to fuck off. You have to stand up to bullies. At the moment she’s the Queen Bee and everyone is afraid of her.

Really, what would happen if you told her to fuck herself?

With the children tbh we don’t see them often. Like a PP said it’s usually birthdays 😬 ironically … in saying that when it nephew bday last year we were invited round but asked to pay for our food (takeaway) two things … DH Bro in law is big in business and takes home c. £750k a year in addition when I have people round for birthdays I cater well and they’re always invited and eat well (pile their plates high usually twice over). This year we have not been available for nephew bday!

Why on earth do you invite them?

You are starting to sound like a glutton for punishment.

MerryUmberHedgehog · 12/08/2026 08:14

My problem would be with the MIL who didnt want to help her son out.

ALovelyPinkUnicorn · 12/08/2026 07:59

Agree with all who say MIL is just as big a part in the awfulness of all of this, do you honestly think she sees yours and (twat)SIL as equal?
I think she would absolutely ditch them if she asked, and no way would I facilitate their relationship with her.

BakedPotatoBeansCheeseColeslaw · 12/08/2026 07:53

I think you have a MIL issue more than a SIL issue. Why on earth did she allow those things to happen?

ShakaWhenTheWallsFell · 12/08/2026 07:52

I think you should protect yourself from SIL and MIL. I know you said that you're only angry at SIL because MIL has since stepped up, however I'd be really cautious of opening my heart to mil and of having any expectations of her to help when future shit hits the fan.

Taking you out of the picture, she priotised her DDs perfect birthday celebration over her DS's need to see his poorly newborn and very ill wife. He must have been scared for both of you, and wanting to support you in your family's most vulnerable moment. An adults birthday celebration going exactly the way she envisaged is not on the same level as that, not even close. Your MIL made a very poor choice then. Be careful you don't allow her to hurt you and your family again.

EnglishRose26 · 12/08/2026 07:43

I would never contact her again, and beyond greeting her at the odd family event I would never bother again. You don't need to play nice. You can just wave and say hello and talk to anyone but her. Don't invite her over, and pull back.

You don't need to be unkind, and always remain civil and on nodding terms, but beyond that she does not get to have a relationship with you.

Dh can organise his own family and tbh this is harder for him op, this is family and it is really crap. So acknowledge his feelings, offer him support and focus on your children and lives, and give them no further air time.

@THisbackwithavengeancebecause she’s still DH sister … but to be honest PPs are right … I have little to do with her now… I focus on my own friends and life… it’s busy.

I have the relationship I ‘need’ to have … DH’s DBs wives so DH SILs literally never come visit and have nothing to do with her. They have the advantage of living about 100 miles away!

SIL is a trouble causer in other ways (a gossip) it’s best not to be involved in her world. It’s uncomfortable being around her ranting about other people as that’s not my nature.

I had a toxic MIL & BIL on my husband’s side. Again not to my face or directly, things like I had to be taken to hospital in an ambulance as I had a medical emergency and my MIL told my husband he should go on holiday without me (we weee on way to airport). BIL was always inviting my husband out and then suggesting that I was controlling if he didn’t go. I’m talking to lad weekends away to Ibiza etc. we had four young kids. BIL also had a wife and children but didn’t think he had to be faithful or present - out every weekend and during the week. When he separated (walked out on family 8 days before Christmas) MIL said it was as ex did not cook him dinner when he came in. He also never learned my siblings/parents names (after I had been in a relationship for 20 yrs with his brother). A couple of years ago I just snapped (I think it was after he asked me my parents names at a family gathering) I knew then that I would not make any effort ever again. I can’t explain but it was “the straw that broke the camel’s back” moment. I did not say anything at that moment, however at another meeting not much later, BIL introduced me to new GF - I was very rude to him (embarrassed him) this led to a massive row with my husband, but I just said to husband, no I have been treated badly by him for years and I won’t pretend it’s not happening any more. You have a relationship with him, I can be polite, I can put on a good front but he is a total sh*t and I won’t pretend otherwise. It also happened that about a year before this he came to a friends birthday drinks and said hello to whole table but blanked me - I told my husband during this row and he said “no way would he have done that” so I said ask your friends - it was fantastic as BIL had been doing that for years but was always cleaver enough not to do in public, until he slipped up. Anyway it’s all settled, I feel free, less stressed and husband happy. I don’t talk about them, if we see them in very polite - we have been on holiday together since and was fine. In a weird way BIL in now much nicer and even recently texted to say he hopes my parent is ok as they were in hospital. MIL I stopped making big effort with. I let all communication go via husband (children birthday gift etc) sorry for the long rant! But basically step back and make peace with the fact that they are not nice and it’s ok for you to know that. Be polite for your husbands sake and all will be fine

2026letsgo · 12/08/2026 06:55

I have an opinionated, judgemental SIL. She made an unforgivable comment when I was pregnant with DS. It still shocks me.
However after 20 years and all our children grown up,I have learnt to gently push back. The reality is everyone finds her difficult not just me and those that cope best like her parents, come from her needing them too. She doesn’t need me of course.
Once I understood her world view it was easier to not get upset.

With your SIL she’s clearly in her own small bubble. Whereas you come from a place that accommodates extended family. Lower your expectations and be proactive with the bits that don’t work. She doesn’t invite you? Don’t feel you should invite her to similar things. It’s not petty or mean, she simply doesn’t see the same value in you or your relationship.
