Sorry you find yourself here, but it's a great place for advice, support and to vent.
Sounds like you guys have some issues. First, the A. You need a transaprency plan in place where she gives you full access to her email, FB, cell phone, txtg - EVRYTHING. NO contact with OM. NONE. NO EXCEPTIONS.
And, maybe I missed it, but has OM's W been informed?
Second, have you guys gone to a MC - not individual C's?
