Child Custody and Harassment by wife under influence of her parents and astrologer

I and my wife have been happily married together since 2019 - It was a love marriage, court registration was done without any dowry. My parents always treated her like their own daughter. However, since the marriage took place against her parents' wishes (she belongs to upper caste), they have always been frustrated and angry due to this as they are arrogant and take pride in everything. According to them, they can never be wrong. They treat our marriage as a great setback for them. They are also very orthodox and superstitious which as an upbringing have been inherited by my wife also to some extent. I have also seen that whenever my wife is in contact with them, under their influence she starts doubting me and my parents and even starts to abuse us without any valid reason because her parents uses her insecurities to manipulate her. May be they do this unconsciously. This has been repetitive patterns and occurs frequently. Then I used to try hard to convince her somehow which always took 3-4 days' continuous efforts. In 2024, we were blessed with a baby girl. The delivery took at my hometown (Delhi-NCR). Everything went very well. However, when her parents visited our home after 10 days of delivery, all things took a U Turn. Out of nowhere, she started abusing my mother and sister and stopped all conversation with us though she was residing at our home in the next bedroom. She used to be with her mother and father with closed door (as it was cold and heater was put in place for warmth of child). One day her mother suddenly decided to take our child to their native house (Kolkata). We were simple enough and cared for the child so we allowed them to go. The real thing started now when she started emitting poisons for me and my family under the influence of her parents. She has been abusing and mentally torturing me since then. She has even told that some astrologer has told them our daughter is in danger and should be saved from outsiders. She even blamed my mother for having an evil eye and my sister for using witchcraft. As a result from the last 10 months she has not even shared a single photo of my daughter with me. Video calls are very rare and that too when I call her mother. My wife has left my daughter with her parents at her home town (Kolkata) and went to join her job at a place 1700 kms away (Chennai). Whereas, I am residing with my parents and have a job in the same city (Delhi NCR) where I can take care of my daughter in a much better way. I have tried telling her about this but she starts abusing me horribly. It is to be noted that I have sufficient proofs of everthing mentioned above. (whatsapp chats, voice messages, photos, voice recordings etc.) As I care for my daughter's welfare and don't want such a poisonous environment for her. I want my daughter's custody without going for divorce as I know that once her parents will be out of sight she would realize her mistake. How should I proceed? Kindly advise.
