How much should I have to pay to my wife If I applied for divorce

Hi Sir, I am husband and I want divorce from my wife because of below Reasons: 1. Wife has denied me proper sleep and food. Every day quarrelled with me during dinner and at sleep. Also, my wife suspect my character. Fight is mainly because I am care for my parents. I need to care my parents being their only son.But, she wants me to separate. Are there any law to protect the rights of old people? I don't have any proves that my wife want divorce and she only quarrel and not me.She also stated that she was not happy with marriage and only forced by her dad.She hates my parents and want them to die. She always blame me that I torture her which is totally false, She & her parents always said that we have spent 25Lacs in the marriage & give a Car of Rs. 5Lacs as dowry - which is again completely a false blame, I have proof with me in which they admitted that - Me & My family never asked for dowry & they give it to her daughter from their own happiness. I get around 20-25K after tax deduction. What is maximum compensation that can be asked by my wife's family
