Divorce

Sir - Im an NRI working in USA. I got engaged in 2015 Nov and got married in Feb 2016. I had tiff, arguments with my Wife right from Engagement. Our parents got involved to sort out differences and we got married. But this continued after marriage.After marriage i traveled back to USA and processed visa for her. During calls i found her behavior weird. She spoke normally,crying,laughing,shouting at me within span of 10 minutes call when we had an argument. We contacted Physiatrist and Psychologist for counselling which didn't help much. Prior her travel to USA our parents, relatives sat together and their parents assured that she will behave well here. She came to USA in October and we are having problems again. 1 month back she cut her wrist and tried to jump out of window in another instance during an argument. I was shocked and afraid. We thought to travel back to india and sort out differences between parents and relatives. She traveled back to India last week and I had some work to complete so i planned to travel after 10-15 days. We found that they were planning to put up a case against me and my parents when I get back to India.I had to cancel my travel and had to consult lawyer. We sent a notice stating her suicidal attempts, her behavior and want to dissolve the marriage. Now she and her parents have come home and they said they will not leave until i come to India. I'm worried about my parents and she may attempt suicide again at my home or put false allegations against my parents. What should we do now? what if I travel to India and they file 498a case confiscate my passport?
