My husband is harassing me for my past broken engagement

Prior to my marriage with my husband I had one broken engagement. Then after 2 month of this incident I got married to my husband.Before marriage my husband's family said they don't want anything. But on the second day of marriage my husband started taunting me for dowry of Rs.30 lacs. But when I said you should have told this before marriage then I wouldn't have married you. Then he very cunningly convinced me that it was not him who wants dowry his relatives are taunting him that's why he said this. Then he started digging up my past and disclosed about his past broken engagement. I also shared about my past broken engagement. Then he became violent and started calling me jinx. Everyday night he pretends as if he has forgotten my past and next day morning again he starts fighting with me for that. Then he left to USA. And demanded divorce over phone. Then after one day he changed his mind. This kind of mind swing continued and sometimes he harassed me for dowry, sometimes he harassed me for my broken engagement. His family members also started torturing me. Because of which I went through severe depression and attempted for suicide. After that incident his parents stopped torturing me but my husband started scolding me day and night for that. Then my husband forced me to throw all the jewelries gifted by my father on his face so that he can accept me with zero. Everyday he fought with me on this topic. Finally I agreed. Then whenever I asked him for initiating VISA request for me he bluffed and gave several baseless excuses. Because of which my sister enquired in his office. They sent to me my house to perform puja for the wellbeing of my marriage. But after that they never took me back. Whenever my father asked for this they gave baseless excuses. When my father sent a letter to his father, his father replied with a letter containing burglary, man-handling allegations and assassinated my character. Which forced me to file FIR against them. Then after one year they filed 2 false cases against me and my family and one divorce case. Now after 6 years of separation. My husband called me for reunion. Then we met each other at several places. Now again he has started harassing me for my past broken engagement and claiming that he's gotten that engagement's photo from somewhere and blackmailing me emotionally and harassing me for that and threatening me for gang rape. Till my marriage with my husband I was virgin. But my husband is always assassinating my character. I love my husband so much. So, I want to know, is harassing wife for her past is legal.?
