Hi tooktheredpill
At the moment my situation is very similar. I am trying to fade gradually and my wife is beginning to see the change.
I was an elder up to November 07 and stood down, ever since I have been playing this double role which I HATE doing.
I have discussed some of my concerns with my wife and she just stops me when she does not know how to answer. Once again i HATE putting her in this position. I recently was asked to do a bible reading at the hall, gut feeling was "i do not want to" but to keep the fade going I had to appear to be still a JW at heart. But i understand your problem - you will be like me and many others, you have zero motivation in helping others come into the org.
Perhaps it is time for a real heart to heart with your dear wife!!!! I do not mean tell her everything but perhaps just say you have your doubts, faith in org is weaker than it used to be and perhaps someone else should take the bible study. In the end, if you try and conduct the study you will find it a real challenge to keep it up.
I love my wife more than anything else, the same as you feel regarding your wife I am sure, but my wife gets emotional when I discuss having doubts about the org. I have tried to break the news gradually and it is getting there.
I suppose above all else we owe our companions in life some honesty but its easier said than done. It is like puling the carpet from under there feet. A few months ago I had had a few drinks and started saying to much, I told my wife about the Child Molestation, UN scandal etc etc. I said I found meetings hard going. She started to well up. She pointed at our favourite painting on the wall, a couple walking through the Canadian countryside, and she said "thats us in the new system", "I want to live forever with you"!!
Well it ripped my heart in two!!! In fact I am getting quite emotional typing this....
I just wanted you to know that you are not alone in your difficulties.
