Fellas is this what we call the hypergamy switch?

My wife has always been a head turner, but recently I noticed that when we go on dates, with other couples I would catch men checking her out hard, where as a few years back they seemed more interested in the other wife, now they are all looking at my wife, and I wonder if it's just the hypergamy switch being flipped, where she is about to be cheating for the first time in her life.
