How can I fight false cases of 498 377 506 etc filed by wife

My wife has filed many cases against me in bareilly.when i didn't appear for mediation because I was mentally disturbed by her violent nature n I don't want to stay with her as she tortured me n my mom very badly.whatever she says I have to do it then n there...if I didn't or I deny or try to explain her the situation she use to threaten me with police cases as one of her relatives is retired ips officer in bangalore.one day she asked to leave my mom I said no...to this she tried to commit suicide right in front of me n threatened me that i n my whole family will go to jail. She has come to Bangalore just to torture me n my family. I don't know how to come out of this all as I married her to lead a happy life bt i wasnt aware that she is such a dangerous lady. I want to divorce her...6 months staying apart n 2 yr of marriage over I m very disturbed...can somebody guide how can I save myself n my family. Any help would be helpful. Any good lawyer in Bangalore West..pls tell ur contact number. Thanks
