Kevin, first let me welcome you to JWD! This website is a great place to find information on the jws. When I was younger someone tried to show me information on Charles Taze Russell, about his involvement with the occult, and how he came about some of his calculations...but you know what? At the time, I didn't even want to look at the information, I was just following the wts' orders to ignore any "apostate" material.
So basically, jws will refuse to look at information and facts presented to them, and if they are truly loyal to the org., even if they look at the information they won't look at it objectively, and they will dismiss them as lies from "opposers". So what happened to make me realize that it wasn't the truth was over the years? Little things eventually started to make me think, certain little things I noticed that weren't quite right, and finally when I heard about the wts' affiliation with the department of public information of the United Nations, that's when I was willing to look at all the other things.
In the end, your wife will only really look at the information if she's willing to do so. But until then, keep trying to give her bits and pieces of information, but not too much such that she will go defensive. Also, another good way is to try to show her things in real life that are contrary to what the jws, for example, showing her that things in the "world" are not as bad as the jws claim they are. Finally, a big stumbling block for some who are jws is that sometimes they have difficulty differentiating God and the organization. So it's important to make her realize in the end that they are not the same.
Hope this helps. I know there are some posters here that are living in a similar situation as you are, and they will be able to give better advice then I can.
