Need a Divorce from Wife

Hi, I am married since 6.9 Years now and don't have any kids. I and my wife fights very frequently on small small issues, the reason mostly is her usual reactions on pity things. Also, since long she is approaching me for a kid but I am mentally not prepared as we don't have a good understanding so it will not only impact us but also child's future. I dined finally for a kid, after listening this she got bursed and started hitting me, i did not reacted and was quit. she then said "she will not allow me to live happily with my family and she will file cases against me by saying I m imputed. Since then, she is every day misbehaving with my family too, I think she is doing it purposefully so that I get reacted and she gets something strong for a case. I want to take a divorce from her but she always gives a Dhamki by saying" She will impose n number of cases on me and my family". I am little worried to initiate this step because I don't know what are the impacts when man file a divorce first. According to me she will definitely files case against me.file Can you Please how to proceed in such situations.
