Wife not allowing to see my Kid and returning to my parents house

Hi, We got married in 2012.In the first year of marriage,there was no problems but she used to keep distance from my parents and brothers. We thought she will take time to adjust.I went abroad with my wife for second year(2013) and there was no issues.?(100% all ok). During third year, i made seperate house and stayed with my wife. After 10 months we had a small fight as both of us abused each other parents. I left to abroad again in 2014 and my wife stayed with her parents for 3 months. Later she joined me happily again and again see no issues. i sent her back during 6th month of her pregnancy to India. Once she landed,she came back with her sister and abused my parents, left within a day. This fight was kept secret by both my parents and wife until i returned to see my 1 month baby. She was taking care me extremely well in her inlaw house till my baby was 6 months and i used to visit every 1-2 weeks.Coincdently my mother was hospitalized for months and was severly sick but my wife never bothered. After 6 months when i asked her to return to my house, she started abusing him with putting conditions like: First make seperate house and then take her. She will not allow my parents to take part in naming cermony. I tried to convince for another 3 months but in vain. She was very stubborn. Then i lost my patience and asked her parents and sister to talk to her else i will leave her. I didnt talk to her for 1-2 months and stayed seperately. My father tried to talk to their parents but they directly called a lawyer who threatened me to make seperate house or else he will create false evidence,put me in jail. This was turning point and i became very angry. Now my baby is almost 1 year and i never visited and no communication with my wife. My wife and parents are blackmailing by keeping child so that i will fall inline.ALso my wife burnt her hand with hair removal by mistake when we were in abroad and there was small scar. There is a chance she might show this as torture against me.Now we are seperated for 6 months.Please advise the legal options.
