We are married for the last 6 years and we have a 5 year old daughter. We were living in a rented apartment and 10 months back we had a quarrel and she left me to her home. I have tried her number many times but she never picked up, she recently changed the number. We were connected in Facebook, recently she blocked me. I had sent a registered letter to her, that came back. I have gone to her home, she used to be with her brothers (parents expired). Nobody were there, I asked her neighbors about, but they do not know anything about. I have tried her brothers number, no reponse. Since she is not working, I have no idea where she is. Now, I am thinking about filing a divorce case. Please suggest if there is any option left.
