We realize this is going to sound like a pat answer, but it is accurate: because he or she wants to. Narcissists do whatever they please, and don't worry about what the people close to them think.
How much longer are you going to put up with it?
Probably not, they would fight over mirror time. ;)
Uhh... no
Yes sometimes it can disappear in time, and is called burnt out colitis
Please let me apologize in advance for my sarcasm, but I wish this were always the case! If all the narcissists paired up, then they would leave all us normal folks alone... Seriously, I did read somewhere (in Sam Vaknin's site?) that there are two particular "types" of narcissists may do well for a time...Was it an inverted narcissist he was refering to? I don't quite remember.(Google: "inverted narcissist maybe?) I also read that there are folks out there that actually like being in a relationship with a narcissist!
Pretty much - they need a worshipper & a scapegoat. Pathetic how they can't be alone so STAY AWAY from them!
You should do some serious self analysis to determine why you would try to have an intimate relationship with a person you have described as a narcissist. Hopefully you will eventually decide that you are wasting your time and should move on with your life and find a mate who is capable of caring for and about you as much as you do about him.
Had great time is incorrect. It would be even better with I or we ,he she or they in front.
Maybe the person that is a narcissist was trying to hide it.
No a narcissist will always be a narcissist. Don't get involved, you are free now. Be thankful you have escaped the worse time in your life and can move on. the narcissist wil try to make it look and sound like he is so much better to her, because that will further his need to make you feel like you don't matter, if you did, you would have treated you well, too. in reality, he is treating her just as bad as he did you, and probably rubs you in her face, too!
The narcissist only wanted needed you to supply their need at that time. Now they have the contract job they don't have a need for you until you have something else that they want that is when they will need you again. If you don't have anything they want to nourish their narcissist supply the have no problem writing you off and forgetting that you ever existed. They have no empathy RUN do not stay in contact with them they will destroy you.

Yes, some things can disappear. By disapear, if you mean visually, sure; it happens all the time.
