DEAR ABBY: My sister-in-law, "Noel," recently confided to me that she's having an affair with a married man. I know this man and his wife; they have a newborn baby. I also learned Noel has been unfaithful many times during her 11-year marriage to my sweet brother-in-law. Abby, although I find Noel's behavior absolutely disgusting, I have no intention of telling any family members about her adultery.
I need advice on how to handle everything she tells me. Noel and I were once close, but I do not want her to think I support or condone what she is doing. Frankly, I would like to distance myself from her. I think she is bad news. What do you think I should do? -- DISGUSTED IN PENNSYLVANIA
DEAR DISGUSTED: Be honest with her. Tell her that you think people are going to be badly hurt because of what she's doing -- and you want no part of it.
