My SIL has previously asked for my advice on their situation and now there's a new issue on the horizon. I'm wondering what others would do?
Her DH is close to his Mum and Step-Dad, who have two other adult children. Shortly after he married my SIL, he mentioned, without prior discussion, that they'd need to "look after" his parents when they got older. SIL was taken aback as she had no idea that was the case - her PIL had professional jobs and she assumed they'd made retirement provisions.
Since then, her DH has bought them a new car and a few other things, with his younger siblings making much smaller financial contributions. Sadly, his SD now has an aggressive cancer and has only been given a year to live. His Mum may not be able to manage financially after the SD dies (and as they rent, there's no house to sell and free up cash).
Right now, the family's focused on making the most of the time his SD has left, but my SIL is concerned for the future. She knows her DH will want to look after his Mum, but there's a limit to what they can afford and his siblings have never been especially generous before. It would also be a tight squeeze if his Mum moved into their house as SIL runs her own business and needs a home office. They can't afford to move.
My SIL is kind and wants to do what's "right" but her DH isn't always logical money-wise. SIL hope that his siblings will step up and they can share the financial support, but there's no guarantee. If you were in that situation, WWYD?
