The statistic is bogus; it was a bit of my off-beat humour (see I used the British spelling). Sorry about the icky humour when you find yourself in this terrible situation. (Now you know why my wife divorced me.)
Based on anecdotal information from this forum, when wives do a quick turnabout, from loving you to despising you, there's almost always someone else involved. Usually, there's a lot of cognitive dissonance and they've convinced themselves, and will try to convince you, that there's nothing going on. "He's just a friend." That may not be the case with your wife, but if I had to bet my hard earned money, I'm going to go with the best odds.
How does that change things for you? Maybe not at all. Mostly, doodler needs to learn how to keep his mouth shut.
