I'm sorry that your wife is a jw. You have gotten a lot of good advices in this thread. She is going to shower you with all informations about other religions: how false they are. If she does, try to share your version of "how the Watchtower is false". If she wouldn't look at it, then you don't have to look at what she brought.
The Watchtower lies to recruit more new members everyday. I was one of their victims. Please read Crisis of Conscience. I read it when I was having my own crisis of conscience, and it really touched me deeply. Since you are not a jw, you may not understand the magnitude of the problems or troubles that your wife is in. From the day one she is trained to defend the Watchtower Society. I just hope she is not brain-washed too much. And remember that you shouldn't be hasty, either.
