"Distraction techniques":

I've read that that narcs and psychopaths use distraction techniques to lure you away from the red flags.

For example, just when you are about to question him, he starts kissing you, or surprise you with a romantic dinner.

Crying is another distraction technique they use. For example, when he sees on your face that you are starting to doubt his "sob stories" about his ex, he starts to cry. You are emotionally moved and your mind is too occupied with comforting him that you cannot use it to sort out his sob stories.
