Wife hates husband's parents and have insulted them off the limits

I got married in October 2016. My wife do not want to visit my parents as I am not posted in another city. As soon as, I make plan to visit my parents, though visit is only for 2-3 days, she acts wierdly and make excuses like she is not well. And if, somehow, I reach my home, she behaves more wierd. She shows least interest. Moreover, she takes all the talks and advices of my parents otherwise. Further, when we live together in my official city, she shows least interest in anything. She doesn't show any interest in any hobby, she doesn't take care of the house, she seldom cook, and she always make excuses not to get intimated. She reports everything, everything means everything like bedroom things to her mother. We are now living separated from last two months. And, I know that I'll not be able to continue like this in future. I have also said the same thing to her but her parents including her not understanding the situation. What should I do?
