Not exposing at work is a very personal decision. I never did. My W and OM were coworkers...
But because one doesn't expose at work, don't think that most people don't know. ...
...
but if someone having a work place A thinks that people don't know, they're sadly mistaken. That kind of thing gets out.
It's just another example of the damage A's do, even if people think they're being discrete. ...
and these other two people are now not going to be considered for a promotion to a nice job because of "baggage".
This is a rare example. in this case both the WS and the AS work for the same company... so exposing to HER workplace is exposing to yours.
I only recommend exposure if the exposure is believed to have a positive impact in ending the affair... exposing to your own workplace does as much damage to you in this case as it does to your wife's affair.
And I certainly don't maintain that exposure should be done by the AS either, in fact its best if its done by someone else.
In your case H4, You may not have exposed the affair yourself, but it did get exposed in the workplace anyways... And as you have commented, it does have impact.
Yes, these things DO get exposed on their own in many cases, I think it was PDT who commented how clumsy people having affairs are in hiding their secrets.
