Perhaps the husband is in on it too by taking advantage of this wealthy guy??

My sister is having an affair with a wealthy older man — and her husband knows about it
My sister is involved with a wealthy man who is 20 years older. Their affair (they are both married) is now on year six as far as I know. My sister’s husband is in poor health. Abby, she told him about the affair. They decided to sell their house and stop living together. Yes, they are still legally married.

The wealthy man insists he loves my sister, but he won’t leave his wife to be with her. My sister says he loves his wife too much to divorce. Is this man playing my sister? She’s been through a lot. I’m thinking of contacting his wife (who is also in poor health) and telling her about the affair. Is this a good move on my part?
