Welcome BrianJ. I was in a similar situation not long ago. You can find my first post HERE I was fortunate enough to eventually help my wife free herself from the religion, though it took much pain, patience, tears and sleepless nights. I assure you it's been completely and totally worth it.
My advice to you would be similar to what's been given already. Do NOT push her hard to understand your point of view. Instead of telling her directly your reasons why Watchtower is wrong in such and such point, tell her that you have certain questions that are nagging at you and ask her to help you research those issues. That's how I did it.
Keep it simple at first. I'd tell my wife for instance that I just find it hard to believe that Jehovah would kill our nice neighbors because they didn't read our publications; that I'm struggling to understand how we can say that only JWs will survive Jehovah's judgement and then set it as a subject for our family worship.
Another time I'd tell her that I don't understand how we can apply such an important chronological significance to Daniel chapter 4 when in reality it seems to be a very simple prediction regarding the Babylonian king. Then we'd study the subject together. During most of our convs, I'd let her do most of the talking while I listened and just continued to bring up more questions.
She eventually realized that I was starting to lose faith and that's when things became a bit more difficult since at that point her instinct was to put up a wall. You've got to work hard to prevent that wall from going all the way up. So go easy on her. When you see the pressure building up, back off. Continue to shower her with affection and love. Show her that you've only become a better husband. Cry with her. Show her that you are not bitter and resentful against the brothers of the org, but rather you're incredibly hurt and confused to be realizing that some things that you thought to be true in reality make no sense.
