No one here can. Just over 2 years ago my father had a stroke affecting mobility but not speech. My sister, brother, and I only were told one month before she passed that my Mom was going to die. Sadly I think men moving on quicker when they lose a wife is more common. He used to do everything for her but now he is of no use to her.
Maybe you could try to get to know her and her children.

However I was not angry with my mother whenshe start dating. When I asked if they were planning to marry I was told it was none of my business. When I tried to worn him about her, he said she was just a friend.
