Can I register a case against my girlfriend's family for ruining my life ?

Hello Sir/Madam, I will try to explain the matter in the shortest time possible. Please bear with me if I am not able to. Thank you very much for taking time and reading my case. I liked a girl since school (2010). We are of the same city. I only told her after I got a job in a leading MNC through college placements in 2014. I moved to the new city. We had always been friends but there was a break of 3 yrs in between. She accepted my proposal only after discussing it with her family. We began our relationship in 2016 with her family's consent. I used to go to her home and speak to her mother and her sister. Everything went very well. In our hearts we were already husband and wife. We had conflicts but we solved them internally and never let anyone know. Meanwhile, I got close to her mother and shared each and every thing about my family. She told me that I had to comeback to our city as she wasn't ready to send her daughter to a different city. I had plans to go outside the country through the my company, I was going to do an MBA, I even got admission in the top 40 college in India. I left all that for her and I came back. I started finding a job in the nearby city as there were no opportunities for my profile in my city. I found a job after 6 months in September 2017. My parents knew about our relationship since March 2016. I used to go to her home, chit chat. I was also involved in solving a few of their family issues. Whenever they had a problem they would call me. They also have a dreaded past about which not everyone knows. I hadn't shared it with my parents as her mother had promised to tell them herself. Now, in January 2018, we decided to setup a meeting between our parents. We set 2 meetings and things were great. Though now her mom had started questioning my earning capabitlity. She knew all my future plans and even my salary but she always wanted more. I In the 2 meetings my father had asked them about their family (dreaded issue) to which they gave a half hearted answer (as I know the entire story). My father got suspicious and asked a person outside. He found a few negative points from a third person. He told me to inform my gf and her family and setup a meeting so we could just sort out. In 2 days the meeting was set and I was in continues contact with her mother. We had discussed everything on how to handle the matter. On the night of the meeting she just blasted at my family for asking things outside. Nothing went the way we had planned. She was out of control. She wanted to know the name of the person who gave my father the information, which my father declined. My grandmother and mother tried calming her down, but she was out of control and even insulted my family. We tried another time of settling the issue by meeting but she just won't listen. She started pointing things about my family and eventually broke my relationship. I feel due to her immaturity I lost my gf and my career. Can I do anything against her ?
