I think that there could be another explanation. It's possible that OM has not told your W the truth about what's going on right now. His W may not have said how she knew.
When my H was in the thick of the A, he tried to play both ends against the middle. Telling me that she knew everything about the state of our R, but she knew nothing. When I finally called her, she was completely floored.
Your W may not know what's really going on. Believe me when she does you'll know. Like everyone else said, the anger is intense.
