Captain Obvious:
Welcome to the forum! I am sorry that your marriage is being strained because you found out the truth about the religion and your wife is having a hard time dealing with this fact. It is interesting that you mention that your wife has "less" knowledge about the religion's doctrines than you do. Meanwhile, she's crying about you and hoping that "you will see the light and come back to Jehovah".
I have noticed something similar with one of my JW friends. She imagines that I will "see the light and come back". And, this from somebody who doesn't even know what the religion teaches currently. I firmly believe that there are a significant number of witnesses in any given congregation who know next to NOTHING about what their religion currently teaches (and dont' really care), and are only there because of an emotional connection to it - whether it be family, friends or even memories of good times past and the new system fantasies.
Let us not forget the religion's magic name, for surely god would have swooped down to obliterate them if they didn't have the truth? Right? These are all the things that keep JWs faithful to this religion and any evidence to the contrary be damned.
Go slow and careful and be patient with your wife. In time she may come around.
