How can I get divorce without paying alimony

I am married for 3+ years. My wife is having a habit of fighting on silly matters. She wishes that I give her 15000 per month, I pay rent, I pay all bills, and I pay for all house expenses. I didn't gave her 15000 rs. She is never interested in going to my hometown. She picks fight with my parents. She does not let me have sex. Since 4+ months my father is facing kidney failure issue, she left my home and went to her parents by her choice. Her father came and picked her up. Now she is harassing me by lieing that I made her go to her parents. Her father threatens me all the time. She puts messages and calls me and asks me to come and pick her up from her home. I cannot go as there is medical emergency at my home, my father needs dialysis twice a week . My wife's always messages me to get her gold back from my home town. I am very much stressed up. My wife is employees and is warning 60000 per month she is M.tech in software engineering. My job is not going well. I have to travel to Rajasthan for my job as the area lacks medical facilities so my parents stay at greater noida since 4 months. Before that only me and my wife was staying at greater noida.
