Child visitation Rights

My wife and I are separated from almost two years. we got married 3 years back in 2016. We got a daughter after one year of marriage. When my daughter was one month old my wife asks me to go her parental home. I respected her wish and took her there. Since then she has not returned back. She demanded me to to come every month there and wear her all expenses. I did it for one year. Suddenly i fealt cheated when she denied coming with me. Last year april 2015, i went her parental home to take my daughter and wife back she, her siblings and her parents abused me. And warned me if i go back their home they will put charge on me for violence. Niether I nor she has taken any legal action. I do not want divorce coz i have no desire to marry again. All i want is my daughter's good health and his custody. I have not seen her from last one year. Now she age 2 years. Is it possible that i keep seeing my daughter every month untill i get her custody. Is it possible to get custody of child without divorse. She want me to file divorce case, that her father called me and told me. I and my wife do not have any kind of communication from last one year. She never recieve my call.
