My brother got married 6 months ago. It was an arranged marriage thru newspaper matrimonials. We observed a few things in the girl's day to day behaviour wherein she came across as a person with very weak memory, forgetful, confused, presumptuous, dismissive, self-righteousand sluggish in nature. The girl's parents and the girl had deliberately hidden the girl's medical history which were revealed to us recently by the girl. She had hypothyroidism since childhood and she also had her gall bladder removed due to stones thru an open surgery. Had we known such facts beforehand, we would not have gone ahead with this alliance. As a precautionary measure we went ahead and took a medical check up in which all these facts were made clear. She was advised to go for a CT scan further to analyze her abdomen for any damages due to surgery. Also to our shock, during the medical, another fact was revealed in which the girl was found to be suffering from bilateral hearing impairment. She was updating her parents of all these developments at her matrtimonial home. Just before the CT scan, she created a scene and humiliated all of us in the hospital and refused to come back home. She called up third party people to meddle in our internal affairs. She also went very aggressive, dramatic and incontrollable. She went completely hysterical and accused us of torture. Her father managed someone to pick her up as she refused our offer of dropping her to her native place. My brother tried to speak to her separately also but all in vain. She just wanted to leave us all. Finally when we realized that she is not going to stay back, we allowed her to go. It has been almost 30 days now and there is no communication from their end. My brother after so much of humiliation at her hands has decided not to reconcile as she appeared as a mentally disturbed person and is uncertain of her behaviour. He lodged a letter also at the local police station stating the events. How do we proceed further?
