What is the ruling of Islamic law regarding a man living with a woman who is unlawful to him in an illegitimate relationship, watching obscene films, and committing adultery, under the pretext of fear of being reported?

Thank you for abstaining from smoking and alcohol, but you erred by committing fornication. You must immediately distance yourself from this woman, either by moving to another place or by returning to your country. Adultery is a grave sin that necessitates immediate repentance and cessation. Allah Almighty said: "And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way." (Al-Isra: 32). The Prophet, peace and blessings be upon him, said: "When a servant commits adultery, faith departs from him and hovers over his head like a cloud, but when he ceases that act, faith returns to him."
