I hate to say it . . . but I do consider it cheating.

Really it depends on your interpretation of the word "is" -- ha -- I mean the definition of the word "cheating".

Is any physical activity between your partner and another person "cheating'"? Some people say so. Still others say that cheating requires an emotional investment.

I'm going through something right now that kind of keeps me from saying my actual opinion. Let's just leave it at this -- its cheating, of course its cheating. But does that mean you don't WANT her to cheat?
