I got married in 1987 and got two daughters aged 27 and 25. My husband appeared to a very calm and gentleman with no bad habits and is well educated and he is a professor. Within a week after marriage itself I realised that he is highly egoistic, extremely stringy, short-tempered and throws abusive words easily. Since I already got married, I accepted him as it is. As the age passed and I started doing well in my career and became a professor, he started too much mental torture when only we both were there. However In front of others, he would show as if he loved me so much. My two children, especially younger one faced a lot because of his short tempered nature. I did not have independence of spending even a rupee from my own earnings. After about 15 years of marriage I raised my voice that I need some money from my earning for my personal use but he refused. I got fed up and finally when he went to Libya on a 2 yrs contract, I took possession of my passbook, check book and ATM card. I did not return it to him back when he came back to India. To put me in control he tried several methods but I did not bend for anything. Finally he left three of us and started working in a different city and stopped financing us. With lot of hardships I took care of my daughters' higher education and now both have settled well in good jobs. I sold my gold ornaments and purchased a flat with a heavy loan. He started speading rumours that I have illegal relation with someone. I have hidden his money and purchased the flat etc etc. He has recorded some of our telephonic conversations and says that he will produce those in the court and prove me guilty if I apply for a divorce.
I have absolutely no idea about the legal issues if I apply for a divorce. He has always given me mental torture, no physical. How can I prove this? One lawyer told me that to get a divorce I need to stay with him for 6 months. But I cannot tolerate him even for a second. I dont need any of his money or property but just want to be free from him legally. Kindly advice me, how to proceed.
