Wife Parents Asking Huge Money

I got married 8 months before and I didn't even stay with my wife for one hour. We did not have first night. Girl doesn't want me and it was a forceful marriage. Girl messaged me "she will suicide if her parents will force her" And I have some of recording that's its a forceful marriage. Now I sent two notices asking my wife to join me and they rejected third notice. Now they are saying to pay 10 lakhs because they spent 10 lakhs for marriage it seems. How can I sue my wife and their parents for mental harassment for 8-9 months and he has given life threatening for sending court notice. He was ex politician and how can I win the case. I will die but I will not give money. What if my wife start lying about me in court and we never stayed even for 1 hours. All our relatives knows about this.
