My ex-girlfriend asking for justice because she thinks I moved on fast & she threatning to complaint

Me and my girlfriend broke up on feb 2021 because of both family disagree with the marriage. My family and her family convinced me to drop out from the relationship. After a week my ex threatning to hurt herself and now her family supporting her. She thinks I cheated her & used her for show off even though I was mentally prepared to marry in simple way and adjusting finacial aid. But after seing her immature act and trying to dominate me, I lost interest in marrying her. After she came to know that I am not responding her. She threatning to lodge complaint and ask for justice. So I decided to clear this thing peacefully and talked to her came to decision that we don't have any commitment and will be friend just like others. She agreed this on march 2021. In may first week 2021, she hear from someone that I am looking for other girl for marriage (anyway I am not focussing on marriage right now), she threatning to lodge complaint and she will ask for justice and drag me and my family to police station. Here, we even though spend 2night together or had romance etc. I never had sexual intercourse with her. She is now telling I should regret that I played with girl's life. So here what are the consequences I must face.
