Spirituality to the JW's equals tasks. We have met so many Elders wives who absolutely need their husband to be an Elder (a somebody in the Congregation).
She should be grateful that you provide well for your family and work hard. Sounds to me like she wants you to be a "somebody" in the congregation. We have seen several sisters in the Hall like this. If there husbands were removed or stepped down they (the wives) would be devastated.
Suggestion...run like hell from this cult disguised as a religion.
