Dear Mr. Dad: I’m an expectant father and something weird is happening. Ever since I found out that my wife is pregnant, my loyalty to her has started to waver and now all I can think about is going out and having affairs—especially with her best friend. I don’t know what’s happening, but I’m in desperate need of help—it’s driving me crazy.
A: Cheating in marriages is nothing new. And although there’s a stereotype that men are the primary cheaters, a number of studies have found that women are just as likely as men to stray. Cheating during pregnancy is actually pretty rare, but thinking about it isn’t. There are a number of interesting theories about why this happens.
