Mental torture by wife

Sir, my wife and i have been married for 6yrs we dont have any children due to her inability to concieve, problems started after few months after marriage , i got to know after doctor check up that she cant conceive upon saying this to her she said its your problem not mine you are impotent etc etc... for this i got her medically checked and the report stated that she is forever unable to have a baby. i told her parents why did they did not disclose this to me before marriage it was an arranged marriage..then i had a spine operation after the operation and during recovery time she would pul up tantrum and regularly use words that i cannot use here..i am now all right and working butevery now and then for menial reasons she would bad moth my mother and sister.. i keep silence as she may lodge a false case against us.. i want to divorce her as i cannot continue with her its torture everyday.. what would happen if i go ahead with divorce procedings do i have to give her half of my weath and what are other things which i should be prepared for
