I don't care if she doesn't want to celebrate certain holydays, or if she still wants to believe in some of doctrines that are unique to the JW.
When I first started cooling off I would tell PYRAMIDSCHEME, "I'm not going out in service any more or to the meetings, but I still want to attend convention." or "I will never celebrate holidays, that's just stupid."
But once I realized there was no truth in the organization--which took a little time--I was ready to celebrate holidays and birthdays and I sure as hell am not spending money on another convention. What's the point?
Your wife came to a profound awareness and you might be surprised how quickly she abandons the rest. As to having children, I hear holidays and birthdays are wonderful things to share with them.
