For a word that can refer to both married people or people in a relationship, you can use cheat, cheater, two-time (informal). Two-time is also used as verb, as reported from the NOAD: He was two-timing a fiancé back in England.
For people who are married, you can use adulterer (which is gender-neutral) or adulteress (when referring to her).
