Cheating?... Vegas Lee and Fun_pair pretty much sum it up!
Being deceitful or disrespectful by withholding pertinent information is just as much cheating, to me, as flaunting it in my face! Relationships are based on honesty and openess. How much of each is a personal matter, but I would consider any corespondence, meeting, etc., without my knowledge cheating. Not that I need to know everything that was said, just that it occured, or was to occur.
In other words, anything done behind the other's back, to me is considered cheating. Why else would it be done in secret?
