This exact thing happened to several people in my parents friend group… it didn’t work out a single time. Whatever issues you have with your wife, work on them or break up but don’t get together with the new lady before you figure out why you would ever think these feelings were anything other than infatuation. I know that sounds harsh but I’ve literally seen this again and again and everytime people got hurt very badly.
Yeah even decades later my brain still freezes when I say eagle in English because Igel is hedgehog in German and pronounced the same.
