Divorce and matrimonial matter harassment

Hi, my wife left our home in october last week, i stay with my young sister & parents. she took all her stuff including all the gifts given to us along with all ornaments. I convinced her but she has made demand of 1.5 crores and wants divorce. she hasnt gone legally but complained to women comission that she wants divorce. though women commission had done counselling but she doesnt want to listen and adamant on divorce she wants 1.5 crores if we want to settle. All this is blackmailing stuff. She is interior designer and earns 30-35000 from her job and more from her personal projects and all. what is my way out. do i have to pay so much alimony in court. House is in my parents name. Pls suggest and guide
