1. Section 497 of IPC says it is a punishable offense for a man to have sexual intercourse with a married woman without the consent of her husband. The man committing such an offense can be imprisoned for five years or more and can also be asked to pay a fine.
Section 497 violates right to privacy as well as liberty of women by discriminating against married women and perpetrating gender stereotypes. On 27.09. 2018, a 5 Judge Bench of the Supreme Court unanimously struck down Section 497 of the Indian Penal Code as being violative of Articles 14.
However it is still a sufficient ground for divorce as ruled by the Supreme Court.
(1) Whoever is a party to a criminal conspiracy to commit an offence punishable with death, 2[imprisonment for life] or rigorous imprisonment for a term of two years or upwards, shall, where no express provision is made in this Code for the punishment of such a conspiracy, be punished in the same manner as if he had abetted such offence.

If there was a threat for your life, you could have given a complaint accoridnlgy instead of giving a complaint for adultery.
