When a narcissist is interested in something you have—attention, love, sex, money, time, whatever—and senses you can and will supply for it (perhaps with a bit of their manipulative persuasion), they will be all about you. They are expert on making you feel special, but only for the purpose of getting what they want from you. They will amaze you with their attention, and seem to be completely in tune with everything you are craving from a partner—and they act that way from the very first date. Unfortunately, it's not genuine. It's all to satisfy their own needs for money, control or sex... and once they have their fill of what they want, they will cast you aside.
