What Judaism Teaches About Cheating (Infidelity)
Judaism considers adultery one of the most serious sins in the Torah. It is included in the Ten Commandments and is one of only three sins (alongside murder and idolatry) that a person must die rather than commit under Jewish law. The Torah prescribes the death penalty for both parties, reflecting its severity. Rabbinic tradition extensively discusses what constitutes adultery and the boundaries of appropriate behavior between the sexes.

What You Should Do

- Jewish: Engage in teshuvah (repentance) — acknowledge the wrong, feel genuine remorse, and commit to change. Speak with your rabbi for guidance.
- All traditions: Consider professional marriage counseling. Rebuilding trust takes time, transparency, and consistent effort. Infidelity doesn't have to end a marriage, but healing requires genuine repentance and hard work.

The Talmud teaches that teshuvah was created before the world itself — Hashem believed in your return before you were born. The gates of return are open now.
