Wife threatening to apply divorce and fraud cases and take away all my wealth

Hi, I got married early last year, after marriage I learnt that my wife had a history of violent behavior and she comes from a criminal family. With time her behavior towards me and my family is going from bad to worse. She has hidden many things about her and her familys past, lied to us about her being soft spoken and later I realized she eventually has married me only for her comfort. Being from a criminal family, she has come strong connections of big political people who practically run the city. Recently she has been talking to and visiting a friend of her which I believe to be her boyfriend and since she has connections with powerful people she doesn't feel any bit worried of all the wrong she has been doing to me and my family. We are very simple people and I want divorce but she won't give me easily. Once she threatened to put false cases against me and my family for harassment for dowry and false case for exploiting and harming her. She is in good terms with a very senior lady who has high up social contacts and parties for women welfare. Additionally she claims to be having contacts with a powerful lawyer who pretty much runs all the big cases of the town. She also have multiple political people backing her and her family. On top of that she threatened that all laws are for women and me and my family will be completely destroyed, she would put atleast 10-15 false cases against us, take all our money and make sure we get death penalty or life imprisonment. We were conned by that girl and her family, they never let us know about their background and potrayed an innocent image about themselves. We are simple people and afraid as we have never faced such a situation. By the looks of it in India this is how system works, she has big contacts also a very powerful lawyer who handles major big political criminal cases, the social worker lady who has high connections. Given that the law is what she says or what she dictates. Here from local policestation to the high court atlease she has contacts and based on that she is very confident that she can just destory me and my family in a whiff. We cannot go to any lawyer here because there could be a chance that most of lawyers must be knowing that powerful lawyer she knows or the powerful political people that she knows. Given that I am not sure is there even a solution for this situation.
