False IPC376, 354

Hello, my ex girlfriend came in touch with me after my marriage and emotionally asked me to be in touch with her. She used to threaten me with suicide and all and used to ask to meet. She had committed to marry his college friend and wanted to be with me untill marriage. Lot of times i asked her to leave me and not to call me and liver her life peacefully but all in vain. Her fiancee called me and i told that i dont have anything to do with her and ask her bot to call and message me. Now she has filed false cases through FIR for ipc 376,354 saying that i have forcefully took her to hotels and had s*xual relations, wherein she herself was sending messages to meet and book hotel and spend time outside with her. How should i put all evidences call record and her sms wherein to proove that nothing was forced or blackmailing from my side infront of police or court. She used ask money for her expenses which i have bank records of transfer. Please help how to fight this and come out of this?
