College professors - definitely a risk for dating students , even though that is frowned upon. Mostly about the availability of nubile young bodies who think you’re special.
Doctors - there’s definitely an issue of unique job stresses that someone also in the profession may understand better. Mostly though I think it’s the issue of nerdy guys who couldn’t get the girl when they were younger, now having enough money/prestige/power to make them attractive to other women. And like police officers, their hours make cheating easy especially if they take night call. So easy to say “I’m on call tonight” or “there’s an emergency at the hospital” and how would the spouse know otherwise?
That being said, I’m having trouble thinking of other med school friends who are divorced. One dumped her husband during residency, but all the rest I’m friendly with are still married after 20-30 years. Maybe I don’t know enough surgeons ?
In our 20’s, a lot of us didn’t have the knowledge to recognize the red flags. We can now though, if we use our heads and don’t get swept up in the emotions. Yeah, my ex looked good, but there were red flags.
