Hello Mr. Dhanesh,
You claim that your wife left home herself. How will you prove that? What you should do is appoint a lawyer and send her restitution letter to return to your home. If she won't reply back then you can show to the court that your intentions are very clean. If you think you don't have to pay her then you are mistaken. Law is woman biased so you have to find all loopholes to save yourself. Send her love letter by e-mail that you want her back as soon as possible. I am sure she won't reply back. Show such letters during counselling in the court. Such actions will prove that she deserted you and you didn't force her to leave.
She has declared in own hand-written complaint at the Police station and Women's social cell that she is not willing to come back. Is this evidence not enough ?
