Wife has filed sec 125 case what should be done to minimze the maintenance

Hi, I am married for around 4 years now and I have a 2 years old daughter. My wife has filed sec 125 case even though she is still living with me, though from last 2 months I have been living outstation due to some work. She regularly keeps on visiting her parents house, out of 4 years of marriage she has stayed in her parents house for more than 1.5 years. She has filed a cruelty case in women cell against me as well that too is still going on. She keeps on fighting with me and my parents on regular. I have asked her in women cell to go for a mutual divorce which she is continuously denying. Her intention is to keep me in stuck with her forever and provide her maintenance. As of now my income is high but since there seems to be no way out of this. I want to know if there's any way to minimize the maintenance amount. I am thinking of either quitting the job completely of working for a lesser income job to reduce the maintenance as I don't want this evil woman to keep on ruining my life at her will. by the way she is a graduate and has worked in a call center for 1 year before the marriage, though I don't have any evidence regarding her job. Also, can I file for a contestant divorce case against her since she has filed cases against me in women cell and in court for sec 125. If there are other options too then please do let me know.
