Welcome Tom,
What a dilema. Does your wife understand what this is putting you through? Is it possible that your wife would read some of this forum?
I "think" if you just declare your agnostisism, that you just don't know...allow her to pray for you and leave it at that.
This probably isn't any help, but it's late here and I get slap happy when I'm tired
Your password shouldn't take very long to arrive. You might have it already.
