There is so much to this story but the bare bones of it are that when I was with my ex we borrowed money from my Mum to pay our rent. We had only paid a small amount of it back when he left me. I had no money, no job, nowhere to live and 3 children to look after.
10 years later, Mum has died and my brother says I have to pay all the money back. I’m happy to pay half but I don’t see why I should pay for my ex’s share especially when he now has plenty of money.
