Divorce

I'm a married girl. I got married 8 months ago. It was an arranged marriage. I never talked to him before marriage which is why I didn't knew what type of person he is. Once I got married to him, I instantly started seeing his actual self which includes him being a big mouth (liar) and have a boasting personality and egoistic. Before he said that he never touched any kind of drink or drugs but on the very same day of marriage he was drunk but didn't accepted it. Was dancing like a maniac and behaving not like a family person but a rude one. I was terribly ill that day but he didn't show any sign of care and continued to think of himself. Next day again he indirectly forced himself on me and never ever for once tried to think of me being ill which made a terrible impact on me about him. Days went by with each day something happening and causing me to resent him even more. I was hoping for a lovely marriage but his behaviour proved me wrong every day. And when I tried to point it out by my family' s help he started acting like a victim saying I was wrong and even framed me for things I never ever even thought of. My feelings for him was long gone but now with his words and actions the resentment for him is way higher than what others think it is just because I chose to stay quite. We have 5 years age gap but still I had to tell him how to behave somewhere and to respect his own parents. But he even said those things which left forever imprint on my heart.i just can't tolerate his even single sight let alone compromising because I gave him more than 10-15 chances but now is the end. I was on the verge of depression but no one cared about my emotions. I was physically used but no one said a word for me but instead got to listen that you have to do it even without your consent.All they thought about was physical relationship but no one cared about my mental health.their faces, those memories and that house still haunts me.i wanted a mutual divorce but they are not willing . What can i do in this situation? And what steps can i take if they threaten us by asking that their son was not wrong anywhere and give proof? What rights do i have here?
