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

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

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.

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

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

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

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!!

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.

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?
