In my opinion both of the people involved in an extra-marital affair are cheaters cheating on the FAITHFUL spouse.
If you know that person is married you have no business getting yourself involved in such a situation.
As mentioned before,if they'll cheat WITH you,they'll cheat ON you. Besides,you'd be showing a tremendous amount of disrespect to the faithful spouse not to mention becoming a contributing factor in the dissolution of their marriage which may have just been going through a rough patch.
Being a friend to someone who is having problems is a world of difference from taking advantage of this person's confusion and frustration.
"Hitting It" just because she's offered it seems to me very selfish and immature.

Brian Griffin: Yeah, about your pamphlet... uh, I'm not seeing anything about German history between 1939 and 1945. There's just a big gap.
