Divorce on grounds of mental harassment

I got married 3 years ago with person of my choice though there were some issues before marriage I still gave him a chance to work those out and he promised he would, however soon after marriage he went back on his words and started trading in shares and losing his entire salary. Within a year his liabilities from banks money lenders friends and family crossed more than 5 times his annual salary he lost all those money in shares and soon after all those people started coming over to our house to demand the money. To take control of the situation I took a loan who's emi is 80% of my salary so that his emi's are manageable. but even after this he has continued to manipulate me, lie. He keeps asking me for money inspite of knowing I have none and when I refuse he emotionally harasses me. He also tells his friends I cry foul as he has not raped me, his friends encourage this behaviour too. Now this torture has crossed all limits as those recovery agents have started harassing my parents who have nothing to do with this. All this has caused me to have a mental breakdown. I want to separate from this person as he is nothing but a cheater. I cannot take this harassment anymore. I had to meet several psychologists due to this as I keep going in depression.
