Hi, PanicAttack. I am a regular Christian, never a JW, married to one. I have been on this board for a while now, and I am getting used to the stages of grief that exiting witnesses go through. You are in the throes of grief right now.
In my opinion, it is a completely different thing to know what is wrong, than from knowing what is right for your life.
You have found out that the "truth" you were hanging on to is a bit of rubber raft in rough seas. You don't know what is sure any more. I am afraid courageous Christianity takes a bit more work than several years' of study from a set of books. It means personal exploration and study. I encourage you to explore your gut a bit, and write down what you know is true and right. Do more reading and research, not just on the WTS, but on philosophy and Christianity generally. Even reading the bible straight without commentary can be comforting. Try the Psalms, Matthew, Hebrews.
I am a bit worried that you are mixing up what is true and right for you (the primary person you are responsible for), and everybody else in your life. Abusive partners and abusive organizations control their members through guilt, by making them responsible for others who should be responsible for themselves.
I feel that I am dragging her down because shes not strong enough to be zealous on her own.
Everyone has to stand on their own faith. Your wife must find her own way, too. Perhaps the organization has never been as important to her as it has been for you. You might find some ideas from Amazing1914's story. He started doing personal bible studies with his family (something the organization recommends), encouraging his family to think "outside the box". He first introduced his family to "independent thinking", allowing them to gradually conclude that they weren't all that interested in attending the Kingdom Hall either.
