Wife is asking for divorce but I dont want It, what can be done?

I m SM, working in private co., leaving on Rent, no property, no parents are alive. Its 2 years of my marriage & have son of 9 months.My wife is of short tempered & demanding. Since our marriage I have been forced to fulfill her demands & she always warns me of Divorce if I will not fulfill her demands. She never compromise & keep asking for money. Now because of some issues of leakage in my current ranted home she has left the home. When I tried to call her she refused to come until I change the Room. I told her its not possible as I don’t have money to spend on shifting. I need atleast 3-4 Months to shift from current room. She denies to return & told me she will not come back & will book false cases against me & my sister under domestic violence/abusing. I called her family for talk at my sisters place but they refused to visit & saying do whatever you can do we will destroy you by false cases. In this situations what should I Do. I love my wife&Child & don’t want to loose them.
