Nri divorce

We both are living together and married since 5 and half years. I am continuing to have problems with my wife. We have no kids. We live overseas and both are working. I want to get a mutual divorce and if not possible I want to lodge divorce from my end. I am a citizen of foreign country and she is permanent resident of foreign country and citizen of India. Married in 2014 1. How do I tell my wife to accept for a mutual divorce. Any tips that she can accept.? 2. Our problems are occasional sex, she is very angry and annoying whenever we have fight, shouts very loudly, she is unhealthy or obese, I don't love her at all. 3. How do I start from my end. I have to take action? I have told her many times that we need to seperate. But I want to take action now. 4. What is the procedure for lodging and do we have to live together or separately after lodging? 5. I have recorded calls and voice rocerdings when we had discussions. Do I need any other proofs that can help me stand the case? Thank you for your time, Raman
