My inlaws included husband is mantally harassing me since my marriage (2years).they do drinks on every weekend and weekdays as well. Husbnd assured me he quite drinks after that I got ready for marriage but he didn't.my mother and sis inlaw controlling our marriage life they do my husbnd' brain wash. They also gave me pressure for complete their financially needs. They even sale my jwelry without my knowledge. I have 3 month old daughter and don't want to give this atmosphere to her. And am working women how can I take responsibility of my daughter alon if file for divorce pls suggest as this beyond my limitation. I feels that m in a trap from my in laws n husbnd as they think I will do everything bcse of my daughter now I have to stay with him at any cost. Want to give them a notice if possible so that they can understand there is law for me. And nobody can play with women's life so easily.
