Christina,

I don’t believe one act (esp. when we are drunk) constitute and demonstrate our character.  My close, lesbian friend kissed me at her New Year’s Eve party at midnight because I expressed I did not have anyone to do that with.  Her lesbian, live-in partner was there on the premises.  Neither of us thought it was cheating or anything romantic but just an expression of celebration and caring from a close friend.

Cheating is more than the act/kiss.  It is an emotion and sexual/physical intent that would distance the other from their partner as I would define it.  If either of you or your partner think it is “cheating” then have a real heart-to-heart on how you trust each other, what are the “rules of engagement” i.e. what behaviors and acts constitute cheating and “bad” behavior.

I believe that we come from Fear or Love in how we navigate the world.  Love begets trust with each other.
