And once she does? If she chooses to stay?
First off, you say "once she does" but the sad fact is many BS's don't find out.
But day she does... Many do leave. So presumably they are exempt from the "waived are stupider than ow theory".
Of those that don't, finances and security espmfor kids are often at the forefront of their decision to stay .... Again, how are they stupid? They've just been forced to make pragmatic decisions.
Or if she doesn't see the clues, which usually are there in some form?
So you're saying wives of cheaters are as stupid as ow because they don't see clues of infidelity? .Talk about victim blaming.
No doubt the clues are subtle. Or they aren't cheaters themselves so they don't see them, of they are trusting, decent people who think wrongly their partner is the same, or their partner gas lights them about any clues ... Extremely common.
She believes his shit, or misjudged his character, what's the difference?
Astronomical difference. Ow knows he's a cheater. Wife, unless and until she finds out with solid proof doesn't.
And there aren't always clues, some people are skilful cheaters.
