Dear Prudence,
My brother-in-law disclosed to me that he had multiple sexual encounters with a married couple in exchange for money. He and my sister are struggling financially, and when he first mentioned that he was propositioned, I urged him to decline the offer because no good would come of it. That was about a year ago; then recently he said he gave in (at least twice, I guess) because they needed the cash. However, he has not told my sister. I am upset that he thought it okay to engage in an affair like this and upset that he disclosed this to me and expects me to keep it from my sister. They have two young children, and I know if I said anything to my sister, their family would implode. Keeping it from her also feels bad because if she were ever to find out that I knew, it would destroy my relationship with her.
