I've never understood the idea of a woman blaming the other woman and I've been cheated on several times in the past. The other woman made no promises to the wife, the husband did. If he strays, it's on him; it's his fault.
I've only ever been the other woman once and that was for a very brief period of time when I reconnected with my ex (now husband), of course I was the bad guy in his wife's narrative. Here's the thing, you can't steal a person and if you gotta keep your man on a leash and 24 hour surveillance, he's not the man for you. But I digress.
I think women get caught up in the competition and cattiness of it all. It becomes a contest between wife and other woman, in the wife's mind whereby she has to prove she's somehow the better woman or some crazy shit.
Loved your article.
