Wife removed mangalyaan and left my home

Dear Members, My wife left me 7 months before with no reason. Her father is not earning and she is not ready to work. She wants me to spend for her family. But i am not in position to help her. I am ready to give some money but not for each and everything. My father in law is spending the money which i gave in gambeling. When i asked this my wife started shouting at me and left my home that i am torturing her After 10 days she given complaint against me in Womens cell under domestic violence. I went for enquiry and they agreed that they received money from me. They demanded all the Jewels and other things which they given at the time of marriage (including her slippers) in written. I have given everything they asked and they returned 2 lacs which they borrowed from me in this 1.5 years. All this i have in written and singed in police station. After 6 months i called her and ask her to come back to my house. She said she is ready to come. But her parents is not allowing her to come. She is not ready to come without her parents consent. In the meantime we met each other without her parenths knowledge and i found she removed the mangalyaan. When i asked to wear it she is not ready to do that. i asked several times but the reply is no. I have asked elder person in my home to talk to her parents. Her parents not ready in talking with us and they said no. After this my wife stops talking to me again. What should i do now. Can i file a divorce case. Our marriage is not registered and now she removed the mangalyaan too and not willing to join me again. Can i file divorce case based on this. If so will i get divorce. What about maintance. I am earning around 30k and have my commitments around 25K. What should i do if she files false complaint again? Experts need your help......
