Hi Captain Obvious, As a JW didn't the WTBTS teach you about loved ones being possessed by Satan to deceive you about the WTBTS? If your wife doesn't want to think about WTBTS teachings, then you are fighting a losing battle against the WTBTS's BITE control by showing her WTBTS false teachings.
You say that you have read/listened to Steve Hassan's books, but have you tried to think of how you can apply his methods to yours and your wife's situation? Steve Hassan's methods rely on unconditional love, the BITE Model, and helping cult members to critically think for themselves. Critically thinking for oneself does not include showing your wife the false teachings of the WTBTS until she is ready to comprehend what you are showing her.
You do not have to directly confront your wife to help your wife to critically think for herself. The more you can keep your wife away from JWs and WTBTS meetings the less influence the WTBTS's BITE control will have over your wife. The more you can encourage your wife to make friends with non-JW coworkers or other non-JWs who you meet the more your wife will be able to critically think for herself. The less you use WTBTS's indoctrinated words and platitudes in your conversations with your wife the more she will think for herself. The more that you show your wife that you are a more loving and caring husband since you are not influenced by the WTBTS's BITE control, the more she may start to question what good is there being a JW.
Have you thought about learning about investing and getting your wife involved. Learning about investing with your wife has three benefits: keeps her from reading WTBTS propaganda, helps her to critically think for herself because everyone has an opinion about investing, and helps you both to have a better retirement. If your wife starts using some WTBTS platitudes to nix her learning to invest, then come back with some counter arguments, like how long has the WTBTS been saying that the big A is coming (about 130 years), how long does she want to live, and what does she dream about doing in retirement.
At some point your wife may start asking you questions about why you no longer believe that the WTBTS is Jehovah's organization on earth. When she does, then slowly and gently ask your wife questions and show her how to find answers for herself using the internet, the WTBTS's literature, and/or the Bible. Do not show her the answers and do not dump to much on her at once. Let your wife's curiosity help her to want to learn more.
Peace be with you and everyone, who you love,
Robert
