I helped a female friend financially. She filed a fake complaint

I am married man. One year back I met one married lady. She is separated from his husband and living with her parents at Jagatpuri, Delhi. We became friends. She told me that her husband and her mother in law do not love him. That is why she left her husband’s house and living with her parents.She asked me to help her financially and she promised me to return the money. She asked me money so many times for various fake reason. I was emotionally attached with her. We went for movie and mall etc. in car. There was no physical relation between us. I helped her for 2.30 L. Out of this 2.30 Lacs, Rs 0.82 L was transferred in bank and balance 1.48 L was given her in cash. All the things are mentioned in WhatsApp chat. In oct 2018 I asked her to return my money but she replied that she will not give a single Rupee. She told me that if I asked her to return the money then she will do suicide. After that she gave a fake police complaint in shakarpur police station. It was complaint not FIR. She put the allegation for “Ched-chad” and “dhamki” for kidnapping her daughter. The policeman called me and I went to police station. I was scared of the allegation she put on me. The policeman told me that he will file a FIR against me. Then we both do mutually settled the case. I can prove all the things which i said. I have bank statement and whatsapp chat. Now how can I take my money back from her? If I do FIR, what will be for her allegation which she put on me ? can I take back my money ? please advise ...
