cheat on
Break romantic vows
To cheat on someone is to be sexually unfaithful to them: He cheated on his wife for years.
The phrase implies betrayal of an exclusive relationship—marriage, engagement, or committed partnership.
You can also cheat on a test or exam, meaning to use dishonest methods to gain an advantage: She got caught cheating on the final.
