Rape in live in relationship

I am 27 year old.A divorce women aged 39 having daughter in 11th class filed FIR against me stating I promised her for marriage and raped her many times with no date time or year mentioned. In 2017 she was my neighbour on same floor in separate portion. on request of my landlord she used to cook my food on payment basis. She was very friendly to me. On Feb 2018 my landlord need repair of of house and asked us to vacate. She inform me an accomodation of same type in near vicinty and asked my help to shift along with her as she was unable to pay that much rent. I agreed and started living in separate portion on same floor as neaghbour and share rent.meanwhile she started interfering in my personal Matter so I left the room in Feb 2019 by telling her lie that I have get transferred from my job. I don't tell it to landlord. She started asking me when will I return and live with her I stated I m busy in my work after finishing I will return. In the mean time I helped her financially also by giving her some money in her account. One day in Sept 2019 she found that I m working in same city she came to my office and created scene. And filed a complained in police that I left her. Which got latter resolved. After a week she filed second complain that she was living with me in live in relationship and I should return. Which was pending she started threatening me either I marry her or she will implicate me in false case of rape. I filed anticipatory bail in with reply came from police of live in relationship.In Nov 2019 she filed third complained against me stating false promises of marriage and rape. I got interm bail from high court. As my anticipatory bail is pending. Police has filed Callan in court in which theirnis nothing against me except. My second land lord saying that we both were husband and wife and living with our daughter. I am afraid as he never asked me that nor behaved like.i shifted with her on believing her. She prepared rent agreement on her name but never showed it to me. I never sign and document never ever mentioned her that I am her husband. She never ever told me that. I am filing quashing of FIR and please guide me is anything against me or not. And what are the chances of success
