Husband Is Forcing Me For Mutual Divorce

Me and my husband are married for 8 years but living separately for last 2 years. In September 2015 , I was bound to leave my in laws house due to their constant misbehaviour, ignorance and humiliation. My husband knows all these but suddenly he is reacting weiredly and does not want to live together with me as according to him he felt ashamed as I left their house but he is not ready to accept the reason why I left the house.  He said it's me who made his life miserable but he never mentioned how. He just want a mutual divorce. This is to mention that we didn't have any problem among us except in-laws problems. Whenever we quarreled, those were only for his parents' misbehaviour/comments/ignorance towards me which I was unable to digest.  I never disrespected his parents and never misbehaved with them but unfortunately I showed my anger to my husband for his parents' misbehaviour. I kept on trying to reconcile the relationship but all my attempts went in vein. Initially he took my calls but suddenly he stopped taking my calls. Similarly, with the passage of time he stopped replying to my sms'es and whatsapp msgs. Many of my relatives tried but result was zero. My parents visited my in-laws but they did not want to accept me and gave so many excuses most of those excuses were not true.  Then in February 2016, after 5 months, I went back to my in-laws' house but they refused to allow me to enter the house. Surprisingly, my husband also reacted very badly on me and said he could not do anything to take me in as this house is his parents'. I stopped contacting him for few months with the hope that he would realise what he did and would come back to me. In July 2016, he suddenly called me up and asked me to go for a movie. I happily accepted his offer and watched a movie together.  We had a good time. On my request, we met once again in August 2016. We talked for about 2 hours and I was sooo happy. But after few days, in September 2016, my father-in-law called my father and told him that they want our mutual divorce and if I do not agree then they will take me to the Court. Though that day has not come yet even after years. I kept on trying by sending msgs/email to my husband with no reply. Suddenly in June 2017, he called me one day for some reasons. We met twice and had a good time. In July 2017, he left his house for his job and went to settle down in a different State in India. In September 2017, I visited his new place but alas he refused to take me in and asked me to go back home. I had to stay in a hotel alone even though my husband was staying in the same city . On the next day,  I left the place to come back home.  I did not want to file any police case or court case against him. But now I don't find any other way out except taking legal action to reconcile the relation or at least want to know the reasons why he took this decision. He never said clearly why he thinks that I made his life miserable and how. No one has found any logic in his decision and there is no parity in his statements. Kindly advise how can this be possible.  JFYI, I am Hindu and a working woman. Our marriage was a love marriage.
