Sorry. I had to respond. My brother is a narcissist and says the weirdest, most paranoid, 
, when he is challenged in any context, or under any stress.
It’s abusive, no doubt. But more than that, mind boggling and delusional. It feels like he keeps random ammo in his pocket, because somewhere he understands that people cannot invest in him emotionally, due to his volatility.
So he strikes preemptively.
Your “friend” reminded me of him. Always working his turmoil out at the wrong time, in the wrong place and with the wrong people.
