I do think it is good advice from DOC above, to pose questions, artfully, to your husband. Done in a way that is non-threatening, as in " Do you know what I was thinking about the other day ?......"
If he is a "You should not question anything about the Org" type it may be difficult.
My personal experience was that I intended to "fade" slowly, but one night I just decided I could, in all conscience, never go back. I just left, cold. I did not know how my wife would react to this, would I lose her altogether ? I had given myself no time to prepare the ground.
Luckily she supported my decision, and left too, though she still misses the Social side of JW life after all these years. And she was slow to slough off all of her JW beliefs, which now she has done. But I was lucky.
Prepare the way as much as you can. Good Luck !
