A great big guilty conscious, that's why! So then, they turn on you, to try to make you feel just as guilty as they are..
It is so obvious, they are feeling guilty, so in order to justify their cheating behavior they get angry and defensive.
they arent happy sexually in the marriage/relationship, the spouse ignores them except to fight or cause drama, refuses to help or team up w spouse, so the one who feels ignored goes out to get revenge. "Ill show her ill get 7 blow jobs tonight by 7 hookers" ED my ***.
... they got caught
That's their way of getting the focus off of them and trying to "justify" whatever they did..
defensiveness and blame . .
If they cheat it's their fault period.<br />
Attacking you is a defensive mechanism where they use to try to justify themselves.
they usually need to justify their actions in terms that make them out not to be the bad guy. they've spent the entire affair rehearsing the argument in their heads, so when they get caught, it plays like a pre-recorded message, which it is.<br />
unfortunately, the imagined argument seldom includes your real responses, so when it actually happens they're still unprepared
narcisstic personalities can't be at fault for anything...
