I want to file a divorce case

In 5.9 years of marriage, I have only spent my life dealing with allegations, untruth and false statements from my wife and her parents. I counselled, made then understand, proved their wrong doing may a time in these years. Every time, they find themselves cornered they would say sorry, we will not repeat this again. But they just can not live without doing this crap. It has been consistent mental torture on these topics: 1) Making an issue on 1st pregnancy 2) Conspiracy in partnership of her mother (I have conversation recording of bad mouthing & encouragement to leave me) - I made her not to be in touch with their family as they are teaching wrong things but after birth of my 1st kid, i had forgiven all and let her be with interact with her family 3) Eloping from home for 1st time: She eloped from my home in vizag when she i left her with my family when she was carrying my 1st baby 4) Suicidal Attempt - this she has done to harass or bend me but to police she said because she failed in an interview she did this 5) Abortion of 2nd kid - She was after my life till i got my 2nd child aborted for no reason, she just wanted kids after 6-7 years (had no logic when asked) 6) On my cousin visit request she said if she come i leave from home, i was helpless and had to lie to the cousin to escape his visit 7) She took good care of my mother when she was ill and i got her to delhi, i specially thank you to her for taking such good care but then not sure happened to her she ill treated my parents and their friend's visited Delhi - then i called her parents told them about her misbehavior they again said sorry and said they will make her understand 8) One day when she was in vizag, she went to my place and warned my mother not to disclose anything to me. Blamed them that they are the reason for the fights - that was the day i told her that you have done so many things wrong in our relationship i kept quiet now you have reached to a stage where you are warning my parents. I do not want such relationship let us depart. then again they said sorry and said they will make her understand. this was the time i clearly told because you are saying sorry i trust you all and believe you that she is not going to repeat what she has done. Neither I nor her should ever discuss the topics happened so far. And so many such incidents continued, it was continuous harassment for me and my family. When her father got brain infection she blamed it on me saying that the reason for her father's illness is because of me. She told her mom that her life is ruined because of marrying me She abused me that I am not the kids of father, i am not worth getting married and having a family. So i asked then why are leading spoilt life with me..she left my home and went to her place with kids. I also do not want to live with her anymore but I want my both kids to be with me. please suggest a way
