Cheating varies on an individual, case-by-case basis, and can involve one or more of these types of infidelity, creating a devastating combination against their primary relationship. Cheating can be a onetime incident, such as a physical one night stand or a casual encounter, or it can be a reoccurring series of events. A man can uphold trysts with one woman one time or several at once. There’s no one correct way to cheat.
