Playing on your insecurities

A thread like this may already exist, but I am just wondering what you confided in your narc, as one of your insecurities that he ran with, or exploited?

I am very self conscious of my stretch marks. I have 2 children, gained a massive amount of weight with my pregnancies and have stretch marks.

When i first met him he would say most women have them and it's silly to be insecure. That turned into him saying things like "Ew, that girl should not be wearing a swimsuit, she has stretch marks" or if we went out with his friends and they commented on his weight gain ( He gained 35 pounds in the first 2 months of dating) he would say "I know! Look how fat i am, I am gonna get f*ucking stretch marks!" Seriously???!!!! Such a monster.
