Been there....called her....H cussed me out (only time in my life he has ever done that). It was ugly. I can say that the OW answered some questions that I had and cleared up some lies, but rather than that it wasn't a pretty situation. Don't call her because she isn't worth your time.
Let your H cool off for awhile...maybe several days. In the meantime detach as much as you can.
