Divorce from wife

My wife is Govt. Employee and i work as private tutor. She earns nearly 6.2 lac per year. She & her father used to threaten me that they will destroy my life with their political links. She stays in different city about 250 kms from my home. My father stays with her to care for her. She used to come on weekend & my father in law used to force me to leave my business & stay with her. He used to come to met me anywhere outside the home & used to threaten me for my family as well to destroy my career. I am suffering from vitiligo & he also used to comment me on this. At the time of marriage they were aware of this & they asked me to show full body to observe the white patches on my body. As there were one or two small patches at that time on my leg they were ready to marry her daughter to me. After marriage they started scolding me. Her brothers and her father started scolding me & threatened me alot of time & asked me to transfer the property to my wife's name. I refused and then they kept on threatening me. I was so stressed that my vitiligo problem has increased. I just want to file divorce from her & need to know how much compensation i have to give to her? Can they harm my family in any way? How to protect my family & my hard earned money from them? Thanks
