i agree with mr prabhakar sir you file application in court and get relief and meet with local ;awyer who deal in family case who guide you
Please do not flee. Take a room in working women's hostel and from there file an annulment petition. Do not forget to mention in your annulment petition that he was threating with some suicidal notes etc. Once you put it in the petition, you would be preempting his any diabolical move.
If that is what you propose, then they will file a police complaint for missing person and they think that you have a boy friend (your second post hints out), they may file kidnapping case against him. But if you live in working women hostel and file annulment case immediately and also can file DV case seeking the relief of 'protection order' (which prohibits your parents as well as your husband not to contact you either personally or telephonically). If you live in women's hostel, you can instruct warden not to allow any visitor to meet you.
