She didn’t even see it coming
A woman who gets caught up in an affair with a married man often bears the brunt of much wrath and mudslinging.
Most mistresses (fuck I hate that word, it’s so derogatory) are NOT evil sirens, or vixens, or any other nasty name that is out there.
Perhaps if you actually took the time to try and understand how the relationship started, or what circumstances led her on this path, then a different picture would begin to emerge.
You would most likely discover a woman, that has been in a vulnerable position, or a vulnerable place in her life, when “prince charming” swoops in, like a fish eagle diving out of the sky, claws out and ready to grab its prey.
He is on target, and she doesn’t even see it coming!
