I had the blessing of chatting with CatieF on the ladies chat and warned her about this. She is absolutely solid and will follow her husband and scripture. She is quite the blessing to NickF.I'll second what @FollowingHim has said above. And take particular care to ensure other women don't get opportunity to have time alone with your wife to turn your wife against you. Perhaps you can encourage your wife to record any "meetings" she has with women who bump into her at the supermarket or whatever(?) You will be able to help her through all the emotional challenges she will face.
The attacks through lies and slander which we experienced was beyond anything imaginable so keeping records will help you a lot when dealing with people. Blessings and Shalom
Praying for the whole family.
