She has my sympathy. It may be worth her reading some of the posts by ex elders on this board to see what it was that caused them to question their faith. The elders have a different experience of the faith from the rank and file so it may help her to see what they do and how they act.
She does need to be very discreet if her husband is firmly committed to the religion it is unlikely he will be open to any talk that questions his faith and it may put their relationship in jeopardy.
I will be thinking of her. I was lucky to be the wife of an elder who also had doubts so managed to leave with our family intact but I know it can be difficult to achieve. For now educating herself is invaluable as is learning from other people's mistakes.
