If hubby said that - here's a strategy.
First off, WT views letters as "spiritual weakness." If they eventually answer, they notify the writer's congregation elders about the correspondence.
So, I suggest telling hubby that you feel that it would be presumptuous for a woman to directly contact the Society. So, you would be more than willing to jointly compose the letter, but to respectfully send it in his name.
Fallout may take a number of months, but it will come - in only a positive way for you (and ultimately, for hubby).
