two-timing
Secretly seeing another
Two-timing is cheating on a romantic partner by secretly being involved with someone else: She caught him two-timing her with his coworker.
The term suggests duplicity—maintaining two relationships while each partner believes they're the only one.
As an adjective, it describes someone who does this: a two-timing boyfriend.
