Dear Amy: My husband and I are both seniors. He works full time and I work part time. We have been married for over 25 years. He recently told me that he is involved in a relationship with a 19-year-old girl. When I pressed him for details, he said that they communicate several times a day and have been in touch every day for the last two years. I am devastated and repulsed by what he told me in his very calm but smug way.
