Wife tried to attempt suicide at her home and not coming back

Today is my first anniversary arranged marriage and I am all alone. marriage is not registered. My wife is with her parents since June 2023 and was at my home for only 4 months. Last month she committed suicide by drinking phenyl after an argument over phone at her parents home. She was not willing to get married at first but due to her father she married me last year. She does not had a good childhood and faced a lot of trouble during her higher studies and blame her father for it. Despite I earning less than 1.5L annually which was very clear before marriage, I gave her more than my earning every month of her living with me my savings are gone . Money is not an issue but she doesn't talk nicely and try to blame me for everything. And her family members are telling after one or two months after marriage only that she will not be coming back to live with me. Any suggestions please sir/ma'am I don't know what to do. कुछ तो बता दो आप लोग प्लीज़।
