I totally understand that it’s upsetting that this man treated you poorly for years and now refuses to help with money.

I am not saying you shouldn’t be upset or have no rights to ask for money. You have good reasons to be upset and are within your rights to ask for a loan to be forgiven. My point was that sadly other people don’t always feel the same way we do. He doesn’t seem interested in giving you that money and I don’t know how much you can do about it.

Maybe go through legal system showing that you are unable to pay it back due to disability? Maybe just pay him tiny amount here and there? People rarely change. He doesn’t treat you well and doesn’t sound generous with money, that’s just who he is. I feel for you. It’s sad all around but that’s just how it is. He is who he is.
