Help! My relative: past revealed, abused, cast out. Legal aid?

Hi, I married 1year ago my wife told me she was forced to do a marriage against her concern and she didn't want the marriage life and wanted to live as strangers, also she refused to take wife responsibilities at home i have waited trusting she would change but within 3 months she had medical issues and went to her home for treatment. after informing all her activities now her father is threating me and my family, also making false allegations against me for all her problems. Now he is demanding to go separately from my parents to send her back. if not they will file case against me in the court and make me and my family suffer. Now she was not telling the truth with their parents about her mindset and acting according to their portents guidance that i am the reason for her medical issues and she was not interested in the marriage because i didn't take care of her well. she have depression and anxiety issues from childhood her mother refused to see her face when she was born, as 5th girl child as they expect atleast 1 boy kid she said this to a doctor. she faces refusal and ignorance in her family she said this too the doctor i dont know the truth behind it. she has chronic gastritis also she is under weight (35kgs still at 27years old) and cant increase weight even after trying for 5 years of medication. Doctor suggested for a therapy but she refused to come with because she already had therapy before which we don't know. . even though we lived in same house but she lived in separate room all the days she was with me. Now due to her inability to handle her father she is acting along with them like i was the one who refusing her. Her father even knows about all these matters to hide is fraud he is now threatening me like police case and court. I did nothing wrong in this except married her. what should i do now ?. And I lost hope that she would change here after.

Hi, My sister was married in 2020. her relationship with her husband was good. He used to come late at home and talk to someone for long hours but was very loving to my sister all the time. My sister became pregnant and during that time she came to our home. She was here for almost 10months during which her husband would visit occassionally. Post delivery, my sister was finding it difficult to manage since this was her first child. this her husband never understood and started flirting with another girl and when confronted, he would just say that he had no intention to get involved with that woman, that woman was like her sister. Later when my sister confronted him he refused to answer anything and would just leave the room. Later this matter was informed to his father who disapproved of his behaviour initially and later started supporting him for his behaviour. my sister tried everything that was possible to reconcile. She even told him to forget everything and start new but she just doesnt understand and still behaves in the same way. Now my sister has come to my home again but still he doesnt realise his mistake and doesnt even take any step to reconcile. Please guide what to do? She has a 1 year old girl. please share your opinion. i have tried everything possible even spoke to his father but he is also adamant that its not his fault.
