Girl threatening me on basis of call recordings when we were intimate

Hello, I had known a girl from 5 years, where in she had told me she is from a diff caste. As i had helped her in some tough times, she became close to me. We used to sex chat and talk but never had sex. She had proposed me but i had clearly rejected due to which she told we will be best friends. She had forcefully gifted me a chain on my birthday. Now when m marriage got fixed, i informed her and she congratulated me as well. From the very next day she is calling all people i know and telling all fake things like we had sex, i had promised marriage and trying to create total nonsense and telling that she wil file FIR as she has recorded conversations when we spoke intimatly. I am totally shocked y she suddenly turned like this. Just heard rules for them are totally in favour. She is trying to call and message me badly. I am ready for any sort of tests as i didnt have any physical contact with her. Can i b accused under this call recordings ?
