<human>: How are narcissists soooo good at what they do? How do they calculate your exact reactions? And how are they so good at covering up there evil actions and appear so innocent?
 
Recently experienced what it's like being manipulated by a narcissist, luckily 2 months in I realised some thing is wrong and that's when I came to find out about the Narcissistic Personality Disorder.  

It was actually frightening to read about them, especially that they cannot love and even more how expert they are at controlling unwary victims who fall in their trap. It's like they are cold hearted calculating robots who have the knack to make people go crazy and at times have the nerve to say that the victim is at fault or worse it the narcissist. 

What more intriguing is the girl who I came to like is only 19 (I'm 20) and yet she was very good at the manipulation. You wouldn't expect some at that age to know how people think and behave, and how to exactly manipulate them. I wouldn't even know where to start!

Although deep down I wish I could help, I know I have to cut my losses since these people can't be helped, but I think it would give me better closure to why it takes to long to figure out a narcissistic manipulative tricks, yet it seems it's like they are born with the evil tools in there hand.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Fell in love with a narcissist, now have to cut my losses. Hopefully knowing how they can manipulate so well would bring me closure.
