Love marriage

Hi. I was into a serious relation with a girl. She had left her home for me as her parents had kept her in house arrest. I was just 20 that time so we decided to get married when i turn 21. Even I had to leave my house for her as my parents did not accept. Howevr in few months my parents accept us and we hired a rented house near my parents house and stayed in living. We approached her parents to get us married to lead a happy life but they pushed us out eavlch time. Now its been 4 years that we are together. Last year i shifted to bangalore for work and since then nothing seems to be working fine between us both. Too many allegations and complaints. She accused me of having relation with someone else in bangalore. She created a havoc there in pune and mentally tortured me of filing a case against me for cheating on her. And many such scenes that couldnt be mentioned here. She was allowed to come stay at my parents house and do anything. Last week I went to pune and told her that i dont see a bright future with her. She now has filed a cse againt me not sure for what. The cops went to my home in pune and asked me to visit the police station as soon as possible or else they will file an FIR. I am worried. Please help. This is just a brief about the story
