Narcissistic Arrogance

Oh yes, narcissists are arrogant!  Here's an example and I'll try to keep it short.  One day when my ex-narcissist lied to me, I called him on it.  He was so apologetic (phony) he practically cried.  (I'm rolling my eyes right now).  But he said "what can I do to make it up to you, I'll do anything you ask"  (blah, blah, blah).  So I gave him a very small and reasonable request.  About a month later I asked him if he had done what I asked.  He said "no".  I asked why not.  He said "I changed my mind."  This is when I reminded him that HE was the one who made the claim that he would do anything.  To this his response was "oh, you took that literally?"
If you are in a relationship with a narcissist, they will suck you dry...slowly.  Look for the signs, the traits and the small stuff.  These are the things that pile up and if you don't get out early in the relationship you will get sucked deeper and deeper into the muck.
