Precaution filing divorce against wife

She has a habit of lying. she said she has done B.Tech from a reputed university and after inquiry, I came to know it was an open university. She said she will do a job and never shows interest or gave any efforts to search a job. She harassed my mother when they both were alone in a home. She kept on lying on small things and giving a false commitment. I had called her parents and told that she keeps on lying in several things, can they please discuss with her and inform not to lie. However, they ignored and things didn’t change. I blessed with a baby boy in the month of May 2016 and she was not ready to come back. I have made several efforts and then she came after 6 months. Again after 2 months in Dec 2016, her grandfather came back and took her with them and said they will back after 7 days. There is some function / traditional event which they want to celebrate. From that day she didn’t come till now. I made several efforts, asked her relatives to educate her and been to her home 4 times with my relatives so they can educate her if required. Things didn’t change. Every time when I use to call her and ask when you are going to come. She always she will come, whenever she wanted to come don’t worry. I asked her what is a problem, she said there is no problem at all. ( I recorded that phone call and given to her relative – to prove there are no problems between us). However, her relatives started blaming us, that why I have recorded and sent that to them. Due to the stress of this situation, my dad got a heart attack and 3 blockages and admitted 4 times after angioplasty. His treatment is going on and doctor’s said it would be like this only, they cant do much. I begged her several times, I said I will do whatever you say, but please come back. I need your support, as dad is not well. I have to look after office and home as well. She never calls me, when I use to call, she never responds and blocked my number on all her family member’s phone. And didn't share any images of my son. When I met her last time in last month Feb 2018. She is saying take another flat in the same society and keep one home maid, she won't do any work in a home if she comes. Only then she will come. I begged her not to ask such things which I cant deliver. I cant leave my mom and dad in this critical situation and my mother’s age is also 56 and she also has health issues. Point 11 for Dad’s health. And I am the only son, I also need to look for a marriage for my younger sister. Finally, I said I have to go to court. She, her father and mother, didn’t stop me on this topic and they were silent. They are not saying anything to her. I am thinking to file a divorce case, but I wanted to know if she can do some false allegation on me? If yes, then how do I do something to avoid them? Like I heard I have to give a draft in a police station and Mahila Suraksha or Ayog. And what I need to mention in that draft?
