My wife is being held in mangalore

My wife went to visit her family here the beginning of October. Forced her to stay in mangalore and give up her job in the uk. We only had a religious marriage not a legal one as we wanted to do the legal one when everyone had accepted us. (Big mistake) They have since turned her against me, said I was brainwashing her against her family and using her etc and how I was awful for her. But when she first arrived they took her passport and her uncle came and removed her bedroom door to prevent her speaking to me. They also send people to our apartment here while I was away to collect some of her things and then later people for the rest of her belongings. I am wondering how I tackle such a thing as her family are very wealthy and pressured her hard, also her uncle threatened that if I came they would say I was trying to traffic her. She also said she didn’t want a case against her family and asked me not to go to the police. I haven’t had contact with her for 2 months now what should I do. I had already met them prior on a visit in 2023 and they said they would give me a year to prove my worth which was a lie. As they said to me at the end of my visit to end things as the family has decided that is for the best. She agreed so she could come back to the uk and then we continued, I advised her not to visit them in India it is to much of a risk but she said her family wouldn’t do that and they have. Do I keep trying to get her back or let her go as she was incredibly nasty when we last spoke but she wasn’t like that the entire 2.5 years I knew her. So out of character it is jarring and she was always the happiest person in the room I cannot imagine what pressure she was under to act that way What do you suggest I do?
