Can she file a case

A girl who is friend of my relative did wrong call to me and started talking to me and I had said her to consider me as a brother after talking for two months she asked me to marry even after calling me as brother and I said no as I was not at all interested in such things but she did not stop calling and one day she met asked to meet her as she was willing to kiss me saying that she would never call after kissing at first I said no but she was irritating a lot by calling and by doing messages always so I had to do that in such circumstances but after that she did not stop calling or messaging me and is always asking to marry her and I had never made any promise and never said that I like her and I even have proofs of call recordings when I said I do not like and I don't want to talk to her and she was still calling. If I proceed legally and file a case on her will there be any problem for me sir? Or if she files a case on me will there be any problem for me? I had never made any promises to her and never had any impression on her which I had said to her a lot of times. Please answer sir
