Sister is angry over a car

Hi
My sister has cut me out of her life because my husband bought the same model car as her! (Different colour). My sister is ten years older than me (she’s 50). I don’t drive, I had no input into his choice of new car. We had a car accident and he needed a new one. We only seen her once a year, live totally different areas, I really didn’t see it being a problem. I heard through family she was furious so my husband contacted her to apologise and tell her it had nothing to do with me! Several weeks later I hadn’t heard anything from her so I sent her a scan picture of my 2nd ivf baby and she totally blanked me. Fast forward a year and she still hasn’t spoken to me. I met her 25 year old daughter for dinner last week and she clarified her mum is still raging and is demanding an apology off me! This is the thing I don’t understand, she is ignoring the fact I’m a non driver, it’s not like I bought the car for my use. She is trying to pin this whole thing on me. For me though this runs deeper on my part now. She has missed out on the birth of my son, ignored my 2 year old daughter, has not acknowledged the baby’s birth and she stopped her husband joining us for dinner last week, told him he’s not allowed to speak to us! I don’t even know what to think, I think the situation is as mad as a box of frogs! Advice would be appreciated thanks

Send her a message asking her what her actual problem is with your Husband buying the same make of car as her & reiterate that you had no say in it at all. Not that that should matter but let her know you think she's being ridiculous & that if she's willing to blank you over something so stupid & ignore your children then she can get on with it & to contact you when she's over her 'tantrum'. It's very bazar behaviour from her. Could it be she's jealous of you having more children when she's had struggles or she's not as happy with her life as you think she is & is envious of you & yours?

How many of this make and model of car, are there on the road? Is she angry at all of them, she is being completely unreasonable. I’d ignore her, until she comes to her senses.

If that's all it takes to cut you dead, I would leave her there. A car! Seriously? She needs to apologise to you for such infantile and hurtful behaviour!!

sister is a nutjob.

OneProudAquaFinch · 03/01/2026 19:57

Well I wonder if she's really being sensible and grown up is her nickname Adam peaty sounds very much like it

She has ignored me on the occasion I sent the scan photo (I thought it was going to be an ice breaker so we could talk about it ) and another occasion after that my husband contacted her husband and he was told he couldn’t reply because he wasn’t allowed to. Family that have had a chat with her have told me that I have copied her and she doesn’t like being copied

Is she 10 years old

What childish behaviour!

What is even more childish IS allowin it to happen
There ARE things you CAN do > dependin on how you would lie things to be

Aimtodobetter · 01/01/2026 20:40

Your sister is crazy and I can't believe its just about the car - but it sounds like there is nothing to do until she gives you some hint about what it really is about.

PyongyangKipperbang · 01/01/2026 19:46

I give it a year before she has a Porsche Cayenne!

If you can afford it, change your car for a higher spec model!

We can have a whip-round…

PyongyangKipperbang · 01/01/2026 17:41

She is special, so much better and high achieving than everyone else....except now she isnt. You have stepped out of your box as the "poor younger sister who would love to be like me".

Pathetic.

Frankly I woudnt give it another thought and if anyone else mentions it simply roll your eyes and say that you will not be talking about it anymore and you wont be apologising for buying a car that suits your needs and your family just to appease her insecurity.

She wants to sulk? Let her! If she continues to bully her husband like that she may find that the high life comes to end before long.......

This makes no sense. She sounds bonkers I've got a sister who's bonkers too & was finally forced to no nc for my own sanity!

Bluedenimdoglover · 01/01/2026 17:08

If this bothers you then you're as bonkers as she is. Nothing you nor your husband can do about this. Just see it as ridiculous - because that's what it is. I'd just send birthday and Christmas cards etc as usual. No apology, no grovelling, no arguing, no bad mouthing her. You are the adult in this.

Daftypants · 01/01/2026 16:45

She’s bonkers .
If my sister showed up in the same car we have currently I would be “ oh wow it’s great isn’t it , so comfy to drive etc , goes a fair distance before needing charged etc “
I even laugh if my sister or SILs show up in the same top or dress and we would probably even take photos 😂

Please send her a link to this thread…..

The car is a Range Rover! Hers is white, my husband’s is black!

Then it’s not actually about the car, and that must be obvious to absolutely everyone involved - loads of people have Range Rovers.

I was imagining that the car would be a very specific dream car from her childhood for this kind of reaction to be justified - like in the Italian Job where the guy buys all the exact models of cars and luxury items the other characters were planning to spend their share of the heist money on.

Honestly, OP, whatever’s going on with your DSis, it doesn’t sound like there’s anything you can do about it (although I would be tempted to trade in the Range Rover for something hugely ostentatious in her favourite colour just for fun at this point..).

FudgeAndGalgos · 01/01/2026 14:18

Sounds like she was waiting for an excuse. It's not about the car, it's not even about you.

PeppyRoseBeaker · 01/01/2026 14:14

She don't sound quite right in the head.

SparklyLeader · 01/01/2026 14:05

Your sister is in menopause territory, so she may either have hormone, or lack of hormone, brain which can make some people unreasonably angry over stupid things, like a car, or she's having a regular mental breakdown and needs psychiatric help. Either way, "she ain't right in the head." Send her the link to this thread so she can at least have a real reason to be upset.

FunCrab · 01/01/2026 13:56

You can choose your friend's but not family.
If you apologise without fully knowing why then that will always compromise your relationship with her.
Your only hope is that she wakes up one day and realises this is a non issue. You would be the best judge as to whether this would happen.
It is sad but she is losing out.
You are not in control of her actions.
Enjoy 2026.
If she wishes to come round she will, you have done nothing wrong.
We all should be reminded of the fragility of relationships.

Thinking about The Fast Show and the man who is 'Considerably richer than yow' when his brother turns up in a newer Mercedes and is outraged.

Donury236 · 01/01/2026 13:37

What a weirdo she is! Does she want an apology from everybother owner? Did she ask the dealership to stop selling the car after ahe bought hers? What a Hyacinth Bucket she sounds.

MomOfTwoGirls2 · 01/01/2026 12:35

Is your DHs car brand new or a later year than hers? So she no longer has the best car in the family?
But batshit crazy regardless…
