Hi Alternator and welcome aboard!
I am here for slightly similar reasons. I have a good friend who is a JW.
Myself, I am a born again Christian so there is a similar spiritual "tension". We have agreed to disagree on issues of faith. I have mine and he has his "religion".
The Lord showed me is will be a long haul with my friend so I need to be patient for at least the next ten years or so it seems!
Anyhow, the Lord has given me other people to intercede for right now.
I recommend you pray for your wife as much as possible. I guess she is praying for you so it will be live Elijah on Mount Carmel.
Let's us see who the real God is, He surely will answer and not be asleep, away on vacation or such!
1 Kings 18:26-27 (English Standard Version)
26 And they took the bull that was given them, and they prepared it and called upon the name of Baal from morning until noon, saying, "O Baal, answer us!" But there was no voice, and no one answered. And they limped around the altar that they had made. 27 And at noon Elijah mocked them, saying, "Cry aloud, for he is a god. Either he is musing, or he is relieving himself, or he is on a journey, or perhaps he is asleep and must be awakened."
I agree, love wins. So press on in love and pray the Lord opens her eyes.
All the best,
Stephen
