I'm surprised this article was taken so seriously. It's obviously meant to create extreme reactions on all sides of the issue, thus encouraging endless debate and a bigass bankroll for the author regardless of his or her true opinion on the subject. It's a cheap strategy, but it's working!

That being said, I feel like the debate is sort of irrelevant. Everyone's got their own preferences in a relationship - one man's frump could be another man's dream woman. Unfortunately, this article paints the "undesirable SO" as an abjectly miserable person to be around, regardless of who you are, and using archetypes like "the boring humorless virgin salad eater who hates everything good and free in the world" was more of an attempt to troll for people's reactions than a literal formula for what causes cheating. We all know it can happen for a variety of reasons, and sometimes no reason at all. This person's personal preference is just not a virgin salad eater.

Which begs the question: If someone really felt this way, why not just be honest and do yourself and salad-woman both a favor and end it - make side chick your main chick, and let salad-woman go find someone who she's more compatable with. All of you will be happier for it.
