Folks skilled in manipulation of the heart know what to say or do to win you over. They aim not so much to love you but to get you to be enamored of them.
Covert personalities are not who they appear to be. They know how to look good but don’t care much about actually being good. By the time you figure out who they really are, you’ve already invested much and a lot of damage has been done.
Amorous narcissists can bowl you over with what appears much love and affection. And you typically come to realize what’s really going only after your heart is breaking or has already been broken.
