Wife tortured me and my family and left me but her family is pressuring to get back

I got married in 2022 after marriage she stayed only for 15 days and said she has exams so asked to stay at her parents home for 1-2 weeks but did not returned for 8 months. I messaged and called her daily to talk to me but she was making excuses for not talking and only asked for money which I gave to her. After 8 months she got back and in 1 month she started shouting at my parents and was misbehaving but we thought that she might take time but will adjust as time goes on. In 2.5 years of marriage she only stayed for 8-9 months with us. She never talked to me like wife only threatening me. after she came back after 8 months in two months only I found out that she had written sucide note. In her sucide note she wrote that her maternal family have Tortured her and no one loves her and that she is living like a corpse and also wrote down that my mother is torturing her but she only stayed with us for 2 months only. She always shouts at my mom and never gave her food or anything but my mom was suffering from health issues so she was at bed rest, but she thought her as her child and never complained her. Her behaviour was getting worst and worst. Now in july she said she wants to visit her parents and wants to stay for three months and went to her parents. After that she never called back. We were continuously calling her back but her family and she was not responding. After 2 months they responded and she said she don’t want to come back and her grandfather abused me and father. So we were all tensed. She does not wants to come back and her grandfather is supporting her. Now in december her parents are asking to take her back. She never fulfilled her responsibility as a wife and there was no relation between me and her. She always tortured her how can I take her back. If I take her back my life will be living hell. Her family is threatening for court cases we are scared and don’t know what to do now.
