Question: why do men cheat then have the audacity to lie about it to your face? 

Answer: (*) Because men are cowards.  We would rather cut off our right arm than admit we don't or no longer love you.\n(*) Because men (and women) have this stupid thing called pride, and it gets in the way.  'Pride cometh before a fall.'\n(*) Because men really hate to admin they are wrong, even when they know they are wrong.  Even when they know you know they are wrong.  Think: getting lost and asking for directions.  It's normally the girl who asks, right?\n(*) Because they (mistakenly) believe the lie will cause you less pain than the (whole / half) truth.\n\nShould you wish to discuss specifics, get back to me, as I've just been there, and might be able to relate.
