Dear Eric: I am 80 years old and have been married to the best possible wife for 33 years. We connect and are soulmates. My question is: why have I recently found myself jealous about her affair with a 17-year-old high school student when she was a 27-year-old teacher? This was mentioned a long time ago in our sharing about former relationships. Why has this reactive jealousy consumed me now? I want to know many details about that encounter but realize that will only dig me deeper into my obsession. My constant rumination is putting a strain on my side of our marriage. What can I do?
