My father is harassing me and my wife

I am a Ph.D student. From the day of my masters degree I am paying money (around 30000 par month) to my father and family just by doing tuitions. But last year when I married (arrange marriage organized by my family) the behaviour of my family began to change. Firstly they began to hate my wife as she wanted to do her graduation then me because I was encouraging my wife to carry on her education, they tried to wash my brain by saying that she is a modern girl and she can never be a good housewife, they do not like her as she was studying and she was not like other wives in our community who always busy for cooking, washing dishes, having babies. We wanted to be different from other people among our local community. That became our crime, then they have put option in front of me that if you want to be with us then you have to stop the education of your wife otherwise you live separately. They gave us a room, bathroom and a place for cooking on the 3rd floor of our house and said that you have to pay 10000rs par month and electricity bill and we will not interfere in your life do whatever you want to do. I agreed to this term, but the term was only verbal there is no written evidence. After that we started living in our own way, but me and my wife always returned to my parents and wanted to patch up with them, but every time they disappointed us by abusing us. Lastly we decided not to go back to them for patch up and live our life as I was writing my Ph.D thesis and she was preparing for her University exam. Suddenly my fellowship has stopped for 4 months and I was unable to pay money to my parents, they keep asking for money then I told to my mother that right now my fellowship has stopped, when I will get my money I will pay you all at once. As I was giving money to my parents from my masters degree time to the current time so I had no savings at all from which I can give them money, they did not believed in my words, they said that you are making savings by telling us lie. I sent my wife to her father's house as I even had no money to carry out our expenses. I was in deep trouble at that time, then suddenly my father starts to abuse me, my wife and her parents by telling that she doesn't love you at all she only loves your money, your father in law wants to have all your money and all other garbage things which is not hearable at all. After three or four days later my parents comes to me told me that if you want to live here you have to pay rent otherwise you can go elsewhere. I seriously did not pay any attaintion to their words. Then next day my father came to me and said if you live this house then we will be happy. Again I thought that they are not serious, they telling all this because they are angry with me. Then after one week he started to say all nonsense thing to me, my wife and my father and mother in law over facebook. He shared my wife's picture on his facebook wall abuses her very badly. And told the other guys on his friend list (most of them belongs to our area) to share this. He also shared some text to the elder brother of my father in law, it says something like that "your brother has taken my son from me, I made my son scientist and now your brother and her daughter is eating all his money. My son becomes a dog of his wife" and so many things. Now after hearing this kind of word from my father, my father in law and his family decided not to send her daughter to my father's house. They wanted me to stay in another place. My father also wants me to throw out from the house, but he also told me that he will not have to live me in peace, he will even go to the court and claim money from me by saying that "he taught me from my childhood and made me a scientist and now after marriage my soon is denying to look after me". But the truth is that I never wanted to abandon my family and I never told them that I will not give them any money. I only told them one thing that right now I am a student and I have to built my career, please do not ask any money from me right now, I will give you when I will have enough money and I will not face any financial problem. When last time my fellowship stopped and I was in big financial problem my parents have not given me a single penny. One thing more from the beginning i have given at least 10 lakh rupees to my father and now in my trouble time they do not want to give me a single penny but expect more money from me. My question is what should I do right now? Actually i also want to leave this house no matter what happens to me. My father is doing all this facebook garbage thing and forcing me to leave this house, and my father in law will not sent her daughter to this house anymore. But the problem is once i leave this house my father and my whole family with their friends and fellows will start harassing me and probably may take some legal action by gathering some people who will talk in favour of him. I know I have written a large thing among which you can find some irrelevant things also. For that I apologize. Please suggest me a way by which I can leave this house and live in peace. But i can tell you one thing as they are my parents i will look after them in my way not the way they want... Thank you...
