The Boss knows about the A bc she is a coworker, she told her husband the weekend I found H/OW in the hotel together in Nov. ex-OW's H left her IMMEDIATELY, and H was afraid he'd tell H's boss, so H did. So boss knew in Nov. but thought it was over at that point, didn't know it was still going until New Year's Eve. My H and the OW still work for the same company.
