Any alternate to handle the miss-use of IPC 498

Hi SIr, I m married and its being only 2yrs. one day Me and my wife had a small miss-understanding and their parents took her away. While leaving she said "I know how to leave without you". Her Parents said " I will not let my child with you". I never called them. She tried calling around end of 3rd month, I did not pick her call. After 3 months they went directly police station with false complaint saying I had beaten her and sent her away from home. Me and My father went to station. And they tried to scare us by telling police to file FIR. We did not bother, Again after 3 months they came back saying to police station again saying, My daughter was harassed for salary. We now took them to Mediation centre. There she is not even accepting truth/mistake. She is now trying to be innocent. She is not even giving commitment like she will not repeat these things again. My parents say to divorce her, bcoz of lack of trust on her. Do we have any law how to handle these things, Tomoro again if she does, my life will spoiled. Not able to trust her and her parents. I feel is this big punishment I m giving for her?
