P.S. Maybe I was not clear and the article says it the best:

"Future faking is a great tool for a narcissist to get and keep you hooked. The narcissist gives hints or direct statements about the future in order to control you in the present. This is a part of 'managing your expectations' of what will happen in the relationship, since if you expect your dreams to come true, you'll act accordingly now, giving the narcissist supply and trust."
