In a very broad sense, cheating involves betraying a partner's expectations about the type of contact they have with others.

When a husband or wife, boyfriend or girlfriend, violates one's expectations about what is appropriate, people feel betrayed.  Keep in mind that relationships are not based on logic, but they are influenced by our emotions.

This is why cheating is difficult to define because people differ in the type of contact they feel it is appropriate for a partner to have with someone else.
