Wife has moved to her Parents house (both working, no kids, Hindu)

Hello, me and my wife are from Mysore and we got married 1 year 3 months back, I had clearly explained to my wife before marriage that we need to share our household expenses and my mother will be staying with me, After marriage - her expectations began to grow and so as my expenses so I request her to share the house hold expense and would have frequent argument regarding the financial issues, now she has left me to her parents house 4 months ago and would return only if I relocate to near to her parents house. My Inlaw are very abusive and I do not wish to relocate as the tensions may increase. -Can I apply for divorce? -What will be the backlash from my wife's end? -Since we both are working should I have to pay any maintenance (no kids) -my wife is abusive towards me and my mother but openly does admit that she dislikes my mother staying with me (she is aware of the divorce law). - can my wife file false domestic violence case - can I file defamation case against the false DV
