How do Jewish values apply to this question, which appeared in the New York Times Magazine, Ethicist column. I am a single woman in my mid-20s. I recently learned from my dear friend that she has developed a longtime pattern of cheating on her husband of five years. I understand cheating happens for various reasons - but if I remain friends with her, am I condoning her ongoing behavior? If I am "anti-compulsive-cheating," do I therefore have to be "anti-her?" I value many aspects of our friendship, but don't see her (or my) views on philandering ever changing. What is the Jewish response to this?
