Wife harassing me and threatening me what legal action can I take.

Me and my wife had a love marriage in 2006 at mandir, and later as per her religious way by her parent and we have two kids a girl and a boy. We are living separately from my parents at pune on my own flat purchased and maintained by me. Due to my wifes quarrelsome and short tempered nature we had to stay separately from my parents to avoid tension and disputes, as she cannot adjust with my parents or sibling. Even though we are leaving separate from my family, there is no change in my wife's nature. She is humiliating me every day. My wife demanding divorce from me along with huge alimony and my flat and she forcing me to leave my home. When I refuse to fulfill her this demand, my wife threatened me that she will file false dowry, harassment case against me. She has also threaten me to leave my own house otherwise she will harass me. Pls kijndly suggest.
