The thing is that the decision to cheat on a spouse is a lot more complex than people like to think it is. While some folks have personalities that are more likely to cheat, they are in the minority.
The decision to cheat has much less to do with things like morals and mostly to do with opportunity. That is, anybody can find themselves in a situation where they might cheat provided the opportunity presents itself.
The single biggest factor in someone cheating on a spouse or not is opportunity. If the dynamics are right, it's not that difficult to (temporarily) forget that they have a husband or wife, and a home life they would normally not disrupt.
I wasn't even talking about the cheating husband, I was talking about the slut who wrote the article.
I,for one,often find myself in a situation in which I could engage in some crime/wrongdoing/slimey activity.
But apart from occasionally doing 5 mph over the speed limit or using my Dad's handicapped placard to avoid feeding a parking meter (I never use it to park in a handicapped space),I don't do it.One has choices.

I think you're right in a lot of cases. We're all so busy these days, the biggest element to fidelity is probably not morality, but scheduling.
