Do you honestly find your wife to be the most attractive lady out there? Or occasionally/rarely and hopefully not frequently, you see a woman who could be waking past you on the street or on the train or in a restaurant etc. And she is definitely more attractive than your wife.
How does that make you feel? Do you just ignore and move on? Or does it get to you?
I do love my wife and I do try to ignore. But not easy sometimes. Ahhhh!
