You have a chance to keep her out of the hell and you wonder what you should do? are you kidding? She is upset, and? Your point? She is going to be upset and she will get over it in time. Why help her in any way attend a dangerous deadly cult that protects pedophiles?
In the meantime, when she is too afraid to go to a place that boasts of all this brotherly/sisterly love where everybody is the same and welcome, you need to fill that time with 'couple' time. Show her how fun and intimate your life can be when the two of you actually have time to conscentrate on each other. Bring her flowers, romance her, go for walks, movies, coffee, go see what the community has to offer, join a once a month dinner club, etc... Keep her so busy she will forget how many meetings she has missed. Start being friendly to strangers you meet in the park and have small talk and find out all the interesting people in the world who are happy, fulfilled and yes, even Godly and moral people who are not jw's. If she decides to go anyway at some point you should still continue to try to do things and make friendships outside of dubs, you will need them someday.
Or you could just say what my jw said everytime we had a tearful jw fight when he was first joining, 'I'm sorry you feel that way' and continue on with whatever it is you were doing and hope it goes away. (hint- it doesn't)
