Dear sir we have two years of marriage. But on 20th oct'18 my wife went to her fathers home happily without any problems. but after too many calls for return back she refused and everybody in her family including her abusing on call and same when we went to her home for convincing her father. her father asking us to make/buy a new separate house for his daughter and after that, they will send her back. including I found some call details from my email which her mobile number accounts have been linked. that she had and lots of SMS and calls in between of 11 PM night to 7 AM Moning often days. when she going from my house all jewelry has taken with her giving a reason that it's a festival season and i will celebrate the festival with wear all pieces of jewelry, so i allow her to take her. But now her father continuously denying that my daughter does not bring any jweleries (120Gms Gold+600Gms Silver)with her.
