Marriage issues related concern.

Hi Sir, My name is Rohit Kumar Das and got married in March 2019. Ever since the day I got married, I realised that my wife is very short tempered and gets angry at the slightest of things and misbehaves with my Mom and Sister. 2 months back there was a verbal fight between my mom and my wife. She abused my mother and to control the situation, I asked my wife to go back to her parental home for few days. I don't have my Father and now she wants my Mom and sister to stay alone. In the past she has also threatened to file dowry and domestic case against my family. I love my mom and sister and wish to take all there responsibilities. Just to be on a safer side, I don't want to divorce her immediately and hence have following questions:- > Before I bring her back to my home, I want her to write and agreement between both of us, that my Mom and sister will be staying alone and they should no way be held responsible for any dispute or problem between us. > She will not abuse going ahead.
