Regarding mnt 125

Good evening sir, i got married on 10 March 2019. she was happily living with me. on 13 aug 2019 she went her home for raakhi festival . there was a critical situation at my home both of my mother and my sis were ill i asked her to come at home. but she denied and forced me that i will come only when you will come to my but it was not possible for me to go there at that time. And when told all things to my father and when he talked to my in-laws the abused not only him but everyone in including my sis. my sis is not living with us she is a MD doctor and have no contact ever to my wife and in-laws. Even then they said very wrong words for her. now she filed case against me under sec 9 of Hindu marriage act and MNT 125. Today was 2nd case hearing i didn't go , she withdrawal case under sec 9 and continue with case under sec 125 MNT. I want to divorce her as she has been used so much bad words against my family which i can not describe them. she even used Word HIZRA for me. what should I do.
