[Slate] I work on a popular television show. I am almost always on set when we’re filming and interact often with the cast. An older actor (married, kids) and a younger actress (dating someone) have started a very obvious (to people on set, at least) affair.
The actor’s family lives in another country, and they fly in a few times a season to visit him. I have befriended his wife. After seeing how close her husband and the actress had become, she asked me to let her know if they started an affair. Now that I have to act, I realize how deeply uncomfortable I am being so intimately involved in the actor’s personal life. I know it’s a betrayal to my friendship with his wife not to tell her about the affair. At the same time, I hesitate to get involved. Advice, please?
