Welcome Untruth. So much good advice on this thread. The common theme is take it slow slow slow and avoid criticizing the organisation.
Everyone's different but something which helped me wake up was completely unconnected with the religion. You might be able to create similar opportunities with your wife. I went to Wildlife Photographer of the Year exhibition, I think it was in 2011. There was a huge, huge photo of a gazelle running directly towards the camera with a look of terror. Behind it were some leopard cubs looking quite evil. The photo, probably because of its size had a massive impact on me. The caption explained that the mother had broken the leg of the gazelle so that she could train her cubs to hunt and that the cubs would soon catch the gazelle and kill it. Looking at the fear on the gazelle's face made me question the whole notion of "looking to creation to see examples of Jehovah's love".
That's just an example. You might be able to create similar opportunities for your wife to ask basic questions or you could use the "if someone on the doors asked you" approach. E.g. "If someone on the doors asked you how to explain how a god of love could have deliberately created a situation involving animals dying in sheer terror and pain, how would you explain it? Couldn't God have arranged to ensure animals got fed in a way that doesn't involve pain and fear"
