How Could One Justify Adultery?, Or is it Unforgivable? Options

[fameONE]

Marriage is serious business!

Well, it should be viewed that way, at least. How could one justify cheating on their spouse? What situation could possibly permit such an act as 'excusable?' On the other hand, depending on the situation, is it possible for a third party to find some sense of 'right' by knowingly getting involved with a married person?

I'd like to hear some responses. It seems like a vague question now, but I'll go into detail a bit more pending the responses I get.

Right, I understand that completely. For both it's an issue of "Am I not fulfilling them (physically/emotionally)?" For women we'd rather have you go off and get whatever you need physically than have you go have an emotional affair with another woman. Because then it's more personal, and becomes "Don't I mean anything? Do they love me?" and is more of a threat. Whereas, if a woman cheats it's exactly like you said, an issue of his manhood or ability.
