Hi,
I am married for 9yrs and having a son of 9yrs in the month on April 08 my wife took my son stating that her father is serious and went to her hometown on reaching their she did not call in the night when I called she says I don't feel like to call and later she said you come her to settle the issue. Then I came to know after a week that she has come back to the same place were we lived and started staying in hostel and put my son in a school over their in her home town. Then she is saying in a mail that she is emotionally depressed because of me. Then she says to put money in her account for sons expense. I have deposited also. Many spoke with her parents and my brother in law also spoke with her she is saying I am not interested to live with him. For 4months she did not come in front of me after that she used to come in front of me while going to my office. Now when I call she speaks. Iam worried how to get back her and to solve the situation.

You have to keep communication going and discuss what is bothering her.Someone does not leave for no reason.As your wife she owes you an explanation.
I would tell her how you feel about her and ask her if there is any way you can repair your relationship.
You must keep communication open and honest.It is the only way problems are solved.
You may need to see a counselor as often a third party who can be objective is the best answer.
