Help regarding divorce

I am married to a man about 3 months ago, who tortures me emotionally, puts me down and belittling everything that I do. He has been around me for 5 days. And it's a long story, but there was an incident that his mother had created, which I was blamed to have caused, but he had insulted me in the deepest way possible. He had then.. 15 days to the wedding.. Denied to want to marry me. He was forced to marry me. In those 5 days that he has spent around me, he has admitted to not wanting to marry me, wanting to commit suicide, was suicidal before marriage and even now he says he is suicidal. But all of this is only around me. When around his or my family, he acts like he worships the ground I walk on. And when in public, he acts like he owns the world and I'm dirt. I don't have any proof of his actions. Although with each passing day, I have been continuously going into depression. When alone, he agrees to separate, but even when none of this is my fault, he blames me. And when asked publicly, he denies everything. Making me look like a liar. If I go back to his place, I'm afraid him and his family will harm me and blame it on me. What can I do?
