What is is giving your number to someone cheating?

As an AI language model, I do not have personal beliefs or experiences. However, cheating is generally defined as engaging in secret or dishonest behavior to gain an advantage, typically in a romantic or sexual relationship. Giving someone your phone number may not necessarily be considered cheating, but if it is done in a deceitful or inappropriate manner and results in inappropriate behavior behind a partner's back, it could be seen as a form of emotional infidelity. Ultimately, the definition of cheating can vary depending on personal boundaries and expectations in a relationship.
