Yup. Had lunch with my friend today, and the instincts were right - trouble in paradise. Spent several hours talking with him, and drove him to the bookstore to buy a copy of The Five love Languages before I dropped him at his hotel (did I mention I can be pushy? ).
No affairs yet (that I could tell - didn't ask) but definitely one of those bad downward spirals going on. Maybe complicated by some untreated anxiety disorder on his wife's part. I also recommended that he secretly read DR - bookstore was out (how dare they???).
Let's hope some of my hard-won education in marriage can help him.
