Forcefull marriage

Friends, Im married for last 6 months and it was an arranged marriage. On the night of our wedding my wife informed me that she is not interested in marriage at all and was forced by her parents to get married. So she dont want ne to think as my wife. I replied her to take sometime to understand first and theb to decide jointly. As the days passed she look like getting improved, but still we used to spend our night in separate room. Last week she has written a letter that she is not i terested in marriage at all and was acting like normal all these days and she is moving out of the home and not to wait for her. I have immediately filled a women misding case in police station and came to know from her compamy that she had gone for higher studies in abroad. There is no proper response from their parents at all. As she married under the force of her parents, does the marriage be nullified even after 6 months? Or suggest me how to deal this as she is in abroad? And we don have her contact too asshe never called us back. But it is avl with her parents hopefully. Kindly suggest.
