Disowning a parent for cheating on the other parent...
My bil cheated on my sister when their boys were 12 and 10. He left her, refused child support and generally caused them to be homeless for a few months. We helped all we could, but they were very poor for years. The boys wouldn't see their dad even when they got back on their feet. Their dad didn't really ask to see them either.
Now, they're 25 and 23. My ex bil is dying. He has terminal cancer. My sister has visited him, forgiven him after he cried and apologized. He's begged to see the boys, but they don't care, want nothing to do with him and say they don't care if he dies, he's been dead to them for years and is a piece of shit for leaving them.
My sister has pleaded with them to go, pleaded with them to go to counselling, because she thinks they'll regret it one day. I tend to agree, but they refuse and won't talk about it. Does anyone have any advice for her? If you were me, would you try talking to them?
