@Murali, Rajiv, Rajan - Thank you all for your comments.
I would like to update on this issue.
As advised by Mr. Murali, I once again tried to talk to my wife and my in-laws on phone. They were adamant and started threatening me. My wife puts a condition that she does not want to stay with my mom. She told me that I should leave my mom in some Ashram and then only she will come my home. SHe knows my mother suffers from arthritis and that there is no one to take care of my mom since I am the only son but still she insisted because she knew that I will not leave my mom.
Again the next day I called her up and said that my mom will not stay with us and she will go somewhere else. I also asked her when should I come to pick up her. She did not answer immediately. After two days I called her, but she started quarrelling and brought fresh issues. I asked her to come home first and told her that i would come to pick her up from her parents home. I informed her the date and time of my visit to her parents home.
When I and my uncle went to pick her up, my wife, her parents, her brothers started threatening us and said they will not send my wife.
I openly asked her whether she is interested to live me or not. She said that she will not come and live in my house, instead I should come and live with her in her parents house. I asked her to send the child with me as my mother wants to see him. But she refused. Moreover, they threatened that they will put my whole family behind jail in false cases.
I have the recordings of the whole event.
Now, I request Ld. Lawyers to advise me what step i should take.
