Divorce

I would suggest better you watch PK (Hindi Film) this may resolve your issues/problem.

I am sorry it will not just resolve it will bring you back in normal mental state level. I am sorry for using such language but try n understand one thing that religion is made by man where as god has created this beautiful world and you should accept the same and move on and stop thinking about the religion.

I would suggest let her read the books of other religion as this will not create any difference in your married life.

Stay Blessed...

A happy marriage has two people who love each other very much and are committed to bringing out the best in each other.” For instance, if your partner is struggling with an issue at reading religious books, you listen to them, talk about the situation and ask how you can support them. Tell her Bhagvathgita, khuran, Bible. All sayings will be good manners only.

Only on the this issue divorce wants means if you see other queries you would anazlye how are other are

means court also see how strong you point is to grant divorce not only religious sentiment but also how much pain you have suffered through this all days and how you tried to solve the issue but there was not chance from other side to rectify 

Divorce can be granted only if it is proved that she had converted to other religion, but mere reading the books of other religion will not pave grounds for divorce.  You can wait  for another year so that you can file divorce on the grounds of willful desertion and non cohabitation.
