Anyway, if you do confront the OM's W...you gotta ask yourself; is this going to make you feel better in the long run? Who knows, she might know already and is just putting up with it.
Maybe she is, maybe she isn't. I would personally err on the side of giving her the information and letting her do whatever she thought was right for HER and her family. If the A is still a secret then that is one of the big draws. The "getting away" with something, take that away and consequences set in and its not that fun anymore. Nothing like a dose of reality to shake things up. Even if she is putting up with it, she would probably at least let him know she knew.
