Want a solution from a whore wife's mental torture..

Hello, I'm Sundar from Chennai. I got married by May 2013. Have a 3 year old kid. Ever since my marriage i never lived a happy life, because of the nature of my wife and her activities. I'm a parent less man who looked after my elder sister ever since my mom expired. She is the one who helped me (in fact protected me during my tough time.) when i stranded alone with out anyone to protect me after my mom and dad expired. But my wife after marriage cornered my sister for everything. I'm not hiding anything, true to my heart i'm saying that my sisters have never do any harrasment on her. But yet she kept on abusing my sisters, to seperate me from them and completely get rid off from them. Slowly she started to compare me on her brother in law ( who came out of his home and live separately with her sister) financially and always ask me to spend more than my earning. her continuos torture never allow me to sit at one job, i kept on skipping my job and my career always under threat. Recently she started to shout at my sister vigorously with all bad words and also me and threaten that she'll go to media and police to file a dowry case against me and my sister. She also used a non digestive words about my sister whom i almost put equal or more to my mom. I got all the bad thoughts in the world, i decided to kill myself or her to put a end to this problem. But it seemed insane for me, when i think about my kid. So despite all my friends, some police and advocates told me about the difficulties of filing a divorce case against her, I did it. I feel it's better to be false convicted as a dowry collector than a murderer or coward(suicide thought i meant). Now i'm ready to face the 498a, DV cases and i'm very much sure that she'll come with that. So kindly advice on this how to be prepared to face such situations. Note : I filed a case on 18th of July. The case is yet to be numbered,it getting delayed because of a protest in chennai court by advocates. So the delay make me tensed everyday and every second. for the last 10 days my wife at her mother house. Now she keep on calling me to come to my home again. But i avoid her call purposely. am i going right way. Please let me know.
