I've been married ten years to my high school sweetheart. We have two kids, a seven year old son and a 4 year old daughter. Our marriage is wonderful and our life style is upper middle class. I have no complaints. None. Recently, however, my wife's best friend whom we've both known since we were kids has confided in us that her husband is having an affair with a co-worker of his and that she intends to soon file for divorce and, in her words, "rake the S.O.B. over the coals". My dilemma? I'm not her husband's friend, but we frequently play a round of golf together. I know with certainty that he does not know she is aware of his affair. I feel no loyalty towards him, but I do have some sympathy for the way he's about to be blindsided. A small part of me wants to give him fair warning, but my years long friendship with his wife has thus far prevented me from doing that. My wife and I keep no secrets, so she is aware of this bit of internal turmoil going on with me. She suggested I curtail the golf outings and I suppose that's one way to handle it. Comments would be welcome.
