Severus, Welcome! You have lots of support here as have ITIS, AlmostAthiest, Kwintestel, and many others who got their mates to "see the truth of the Truth(TM)"
My only words of wisdom: Be patient and gentle, loving and kind. Show your support of your wife in whatever you/she does. She's already thinking and acting on her thoughts and beliefs. I doubt it will take very much.
