Sorry this is a long one! MIL gave one grandchild £4k for a car about 10 years ago. She then promised to do the same for all of the grandchildren. MIL gave one of my children the same amount last year - obviously second hand cars have increased quite a bit over the last ten years so me and DH gave our DD a bit extra so they could get the car they has their eye on and made sure it was good low mileage and had no problems. Then this year MIL didn’t give our other DD any money towards a car, no other reason why - just that she thought our other DD should wait another year as she’s still at the local school sixth form rather than needing to travel far for college. This seemed to me and my DH to be a bit unfair - we treat our kids the same whatever, so we decided that we’d buy the car this year anyway and so we paid for the whole car price from savings. When MIL found out she was really unhappy. She has no money worries after being left a rather large amount from her great aunt - I’d not really known how much but she often remarked about it and how she gets taxed so much now on her pensions, etc. so I think it’s not due to lack of funds. She then has given us £2k towards the car, but when she found out that I was paying for my parents to have a new bathroom (my parents can’t afford to pay on their own as low pension income and I’m happy to help them as they need a safer walk in shower and not a bath) and MIL said she wasn’t giving me the money towards a new bathroom for My parents. MIL was being really nasty to me on the phone about it even though she knew my mum was in hospital having a hip replacement that day and I was worried about her - but she said I’d made her and my FIL really cross. I explained that the money she gave us was towards our DDs car that we’d already bought from our savings and that we were paying for my parents bathroom from a different pot of savings - but she just wouldn’t stop saying that she didn’t give us the money for us to spend it on a new bathroom for my parents. Anyway, to make her understand said that I was definitely only using my savings to help my parents and she could have her money back and I’d still be doing the bathroom improvements regardless as it was from a different pot entirely and I’d be doing it even without her £2k. So my DH transferred the money back to his mother. DH was quite cross as I’d been upset about my mum being in hospital and I didn’t need the stress. So we’ve paid for the bathroom improvements from my savings and my MIL now is just acting weird about it all still. I think it’s weird how she treats her grandchildren differently from each other - am I being unreasonable to think she should treat them all the same? It’s really damaged the way I think about my MIL - and my DD still doesn’t know that she didn’t get the same from her grandparents as the other grandkids - she thinks that her lovely granny gave her the majority of the money for the car rather than it being from our savings. Don’t mix family and money seems to be the best way forward!
