AIBU to think my SIL's influence will fade without my in-laws?

Last week we went for an in-law lunch including my PIL, SIL and her partner. I have come away, as per usual, feeling insulted, ignored and despised and it has lingered for a few days. I am sick of it.

My MIL and SIL are in constant dramas with their extended family. There is always some falling out, someone crying over comments made to each other and petty feuds. They constantly bitch about the women in their family saying babies are ugly, people are stupid and got rubbish jobs, laugh at how someone has aged, and spin a small comment into something massive. The things they say about the women married into the family are just awful.

My MIL has a very cruel tongue, and has always been the matriarch. Her DC and DH are terrified of her. A few years ago she openly started encouraging her DD to take over her matriarch role and all of a sudden she started telling us all what to do, and being extra rude to me. MIL wanted every interaction to go through SIL. When I saw what was happening I nipped it in the bud straight away by refusing to engage. Since the coup failed, they have really hated my guts!

My MIL is now late 80's and the wind has gone out of her sails. She is no longer able to bully anyone. Again I have noticed that my SIL seems to think that she is now head elephant in the family, is on a power trip and talking down to people. Her power seems to come from the fact that her parents favour her over my DH and his other brother (although he lives in Australia so he is not really on the scene). She is like a spoilt child who thinks that she can do and say what she wants because PIL will always take her side, even if she is in the wrong. PIL would not speak to DH and I for ages if we upset her. This is why we do not rock the boat.

What I just don't get is why my SIL thinks she can position herself as the matriarch in the family? She is not married, doesn't have kids, doesn't speak to her cousins, hates me and my other SIL in Australia, my kids can't be bothered with her, and her partner is an idiot. I don't think PIL will be here for much longer as they are both unwell and late 80's.

It is funny because whenever we arrange to meet PIL and SIL, she has a massive makeover beforehand. MIL used to do this too up until a few years ago. It's like they are in competition with me. It is so tiring.

So, my post is really to ask for tips for dealing with my SIL moving forward. I'm just so tired of this ongoing saga. I have cut back the visits a lot, but they still leave me reeling. Honestly, I have that line in my head "will no one rid me of this turbulent priest". I just wish she would f'off. 😩It's like there is an imaginary pecking order and she desperately wants to be at the top of it, with MIL's backing.

AIBU to think that when my PIL are no longer around my SIL will suddenly find that her power battery no longer works and that she doesn't really have anything to be the matriarch of?

I just wish we could all get along nicely like I do with my other SILs and female relatives. No competition, just friendly and loving support.

You seem to like the drama of it all. A lot of people just wouldn't have bought into all this palava in the first place. Don't see her! They truly only have power over you if you allow it. You're saying after PILs pass you will start challenging her. What is the point of that, just disengage from it all now.

I would pitty your SIL. She's probably thinking she's ruling the roost now that your MIL is aging and this is the most important she has ever been in her life.

I think you're doing all you can do and you're right now - once the in-laws are gone she wont have anyone to validate her nonsense.

Until then I also suggest the grey rock method with her. I know it would of been nice if she would of done x y and z and you could of been more etc... but that will never be unless you agree to live by her rules and it does not sound like you want to.

She is going to be a complete nightmare when your in-laws eventually do pass. So be prepared for that.

diddl · 20/07/2026 16:11

They have form for saying they’ll change their will if someone doesn’t do as they’re told.

They might leave it all to SIL anyway as they don't like you!

Bredaa · 20/07/2026 15:55

Do you think you will detach / withdraw @DecadesLongSagaor just put up with it?

AcrossthePond55 · 20/07/2026 15:40

@DecadesLongSaga

You think SiL's 'influence' will fade when your iL's are gone? Nope. She is the anointed Queen-Bee-to-be, anointed by the Queen Bee herself, who is now slowly abdicating the throne. When iL's are gone, she will get even worse. I really don't think you're going to change that because it's 'favorable' to SiL. She gets what she wants, why should she give that up?

All you can do is 'refuse to cooperate' as it sounds like you're doing. But if you really want to get her goat, laugh at her. If she issues a 'royal command', laugh and say "Oh SiL, you know I'm not going to do that/be there" and keep repeating it. If she talks nasty about other family, roll your eyes, sigh, and get up and say "I think I'll go for a 'walk in the woods'" (that's my family code for "I'm not listening to you blather") and just leave the room. Let them threaten to get the family to 'gang up on you'. Would the family really do that? Or would it just be lip service to The Royal Family whilst secretly telling you they're out of line. And who knows, you may start an actual revolution! And if they do truly gang up on you, well, you haven't really lost much, have you, because they wouldn't really be 'family' at all in the real sense of the word.

As far as your DH, he's going to have to manage his own relationship with her and his family. And you need to let him, and help him if he asks, so long as it doesn't impact you or your children. That is where you are allowed to draw a hard line. And stick to it.

You're right OP - once your PIL die you won't even have to see your SIL, let alone be subject to her ridiculous delusions of grandeur. How's she going to be 'the matriarch' anyway, when she doesn't have any DC? She will have zero role to fulfil once your MIL dies - and thank goodness for that! Any time she tries to organise things or boss you around you can tell her to get stuffed.

Edited

You are right in that she seriously has delusions of grandeur.

I think my PIL have outsourced everything to her, including looking after their money and POA. My DH is a little reserved in going head to head with any of them as I don’t think he wants to be cut off. They have form for saying they’ll change their will if someone doesn’t do as they’re told.

I’ve told my DH that he shouldn’t trust his sister not to manipulate his parents into handing over sums to her, but I think he is very naive. I don’t care what they do with it TBH. No sane person banks on inheritance. Also, I think both my PIL will end up in a care home within the next 3 years. If they do I’m sure she’ll have a hissy fit about her inheritance and hassle my DH and his brother to cough up for it.

I do think that since MIL is no longer able to keep up the toxic narcissist bully, her DD has taken over the role and doing it with relish.

Specialagentblond · 20/07/2026 15:16

Yes her power will fade. Just go low contact in the meantime and concentrate on your relationship with your husband.

Rosegard · 20/07/2026 15:09

So you have tolerated this for decades because of your weak husband eho stands by and allows it?
Why would anything change.
Your poor children, exposed to such toxicity.
What a legacy.
Them watching their parents being insulted and humiliated.

Madness to have remained around it.

saraclara · 20/07/2026 13:21

Once your PILs have died, surely there'll be absolutely no reason for you to see her? Will your DH want to? I can't imagine why he would.

I can't imagine why he sees his parents tbh.

Certainly no idea why Op doesn't leave him to it!

Mulledjuice · 20/07/2026 13:10

Every time I read one of your update posts explaining what they do i find myself shrugging.

Find your shrug.

Imagine the liberation that would come from not having to socialise with nasty people who see the worst in everything and are trying to hurt you.

If you were to make a list of ways to spend your time, would they make the top 1000?

But you know all of this and yet you're doing it anyway - so what's the blocker? What's the "but" in your head?

I agree with this, I just don't understand it. Why would you set yourself up to spend time with toxic people? They're not the boss of you, there's no law which states you have to attend lunches or other social gatherings with people you don't like. It doesn't matter who they are or who they think they are... there's NO power there, they have no right to order you to attend anything or put up with their behaviours. You don't have to, so why are you choosing to? If your husband chooses to, let him. You're all adults with agency. Consider how much happier you'll be without them in your life!

Pallisers · 20/07/2026 14:49

Your sil behaves like this because she was reared to think it was normal. You are right that she will run out of steam when her parents die. and luckily she doesn't have children that she reared in the same way/fucked up.

But you don't have to put up with being insulted, ignored or despised. No big drama just quiet quit. One time you'll have a prior commitment to lunch, another time you'll feel a little ill just before and won't show up etc etc. why go to meet people who don't like you and show you this? I doubt your dh needs the support. Just drop the rope.

zurigo · 20/07/2026 14:39

godmum56 · 20/07/2026 14:06

but why not do that now?

She's said she doesn't want to alienate her PIL (or her DH doesn't). I wouldn't have anything to do with any of them, personally. Life is too short to put up with this kind of shit. But many posters choose to martyr themselves!

Poppycorn123 · 20/07/2026 14:36

Why would you want any contact with them? I would cut them all out apart from the brothers & their wives. No need to put up with it any longer.

Shadesfiasco · 20/07/2026 14:34

I agree that she will be isolated and irrelevant after her parents pass on. They all sound very soul destroying and mean spirited. I don't think you have anything to lose by stepping down to the very occasional meet up as this is so toxic for you. But yes it would seem to have a clear end point.

KojaksLollipop · 20/07/2026 14:27

You’ve given them too much power already, you need to shut them down as quickly as possible every single time you’re faced with nasty or controlling comments. It’ll be hard the first few times but you’ll get used to it, and so will they.

Harrysmummy246 · 20/07/2026 14:23

You're enabling this by putting so much thought into it.

Floratheexplorer57 · 20/07/2026 14:13

The situation will change when the in laws die and you are right to think her influence will fade.

Be prepared for your husband to never really understand it from your POV however much he loves you. He was raised in that family system and so it is what he might think of as normal.

Yes, this is true.

BigRedLorry · 20/07/2026 14:13

My DPs father is like this… opinionated, rude, ungrateful and thinks he’s the boss of everyone ( he’s 91 btw, disabled, ex forces) He does the ridiculing that your SiL does, behind the family members backs, playing one off against the other. Drives me mad!

His wife is so lovely, sadly got a terminal illness so doesn’t notice a lot of it going on.
Ive found over the years, that to just not go to the events, get-together etc, is the best way. He actually ordered me to a “special” party😱 - that didn’t work! I informed DP that I was 60 years old, had brought up a family and was capable of thinking for myself, and I wouldn’t be ordered anywhere by a man who I was not related to in any form! He pestered DP about my absence so in the end DP told him what I’d said… he barely acknowledges me now🙄

Just don’t engage, don’t attend things if you don’t want to. Invent illnesses, do whatever you need to stay sane!🌺

Her power battery doesn't have to work now , if you don't let it.

I would not spend another second in her company if I were you.

Livelovelaughfuckoff · 20/07/2026 13:54

I find not spending time with people who actively despise me solves quite a few problems. Your DH can have a relationship with them independent of you. Why do you need to deal with her at all, just don't have contact. It really is that simple.

Isometimeswonder · 20/07/2026 13:53

This is so simple.
Don't spend another minute with any of them.
If husband wants to, that's his choice.

Magicpaintbrush · 20/07/2026 13:39

She can only be 'in charge' if you allow her to be. Same with PIL. They sound absolutely fucking horrible. How would you DH feel about going no contact? She can boss you around all she likes, bitch all she likes, but if you tell her to fuck off what's she gonna do about it???
