What to do if wife threatens false allegations to stay together?

Hi Sir, I married a girl whose age is 23 as of 31/10/2001, and my age is 20 as of 30/03/2004. She is older than me. We got married on 10/05/2023, and the marriage was done with the mutual consent of both our families and with our individual consent. However, at one point, I disagreed to marry her, and she threatened me that if I didn’t marry her, she would accuse me of her suicide, rape, and other allegations. At that time, I was unemployed and just a student. After one year of marriage, both of us had extramarital affairs, but she decided to stay with me. Now, I no longer want to live with her, but she has started threatening me again, stating that if I don’t stay with her, she will file cases against me for alimony, rape, domestic violence, and many other allegations. I am still unemployed and continue to study in Bhubaneswar, Odisha, at KIIT ITI College.
