Narcissistic Personality Disorder - This so accurate. I got out. I was called crazy. What I was - pregnant and that's what saved me. Under no circumstances was my baby living in this scary, smiling even, abusive, hot mess.
I think this is a characteristic of the sickest type of narcissist, the malignant narcissist. You won't see them coming until after they've left a trail of destruction.. much like a sociopath. They become enraged when their 'mask of normality' slips and they're exposed or called out... you'll know immediately ! And they won't try to hide it from YOU anymore, only attempt to discredit you so no one believes what you saw in them. Very scary people.
