My elderly Mum gave me and my sister and brothers some money last year - not enough to pay off the mortgage or anything but enough to pay off credit cards and get work done on the house which was a great help. Since then she's been ill and is now asking for it back as she's fretting about her financial well-being and paying for care in the future. This is despite the fact she still has a lot of money (half a million in cash and her house) and that I've shown her calculations that show she spends less than her income and that she has plenty to pay for all her likely needs in the future. I have also said whatever happens we will cover her costs and take care of her.
She says it every time I see her and I'm feeling I ought to give at least some of it back but neither my sister or brothers (who see her less often) feel inclined to do so. I just feel really horrid every time I see her. I could still give her half of it back but if I have to give her the lot I'd have to take out a bank loan. AIBU to not pay it back?
