Welcome to JWD, Kevin.
We are all here trying to figure out ways to reach our loved ones/relatives.
Steve Hassen's first book on "Mind control" is good because it doesn't mention JWs but shows the same tactics they use.
Your wife is being taught that no matter what be loyal to God's organization?.
Read other's experiences here and how the lack of love finally made them look at their organization. Or Raymond Franz's books, Crisis of Conscience or In Search of Christian Freedom.
The UN scandal that was exposed here on JWD. (The WTBTS was an UGO 1992-2002) And how the WTBTs lies to cover themselves.
All you can truly do to help your wife is show her unconditional love. The JWs don't. You have to abide by their guidelines to recieve their love.
Good luck. Sorry there is no magic answer, but we are here to listen and sympatize. (been there, done that)
Joy
