I agree with PDT. Or your W was embarassed at being confronted that way and tried to switch the blame to you.
You shouldn't have taken the time to go through the records with her or validating anything. Best thing would be to have just said "if that's what you believe" after her accusing you of being "controlling" and then left.
The OM could have been lying to his W because he got caught and wants to convince people your W is crazy. The OM in my sitch did the same thing and then I turned it around on him.
Whatever you do, don't engage to be pulled into another confrontation.
