How does a narcissist behave when she is very jealous of a close friend?

They will be very petty snd try to put you down in ways that they think they can get away with (passive aggressive tactics). They will say things that have a double edged sWord meant to hurt you. They also chose to do this when you are out somewhere and no one can hear. I once had this friend who was fat. I was very slim and still am. When I was pregnant she wanted to see my stomach and she looked and goes, "oh you don't have very many stretch marks." The thing is I never got even one. She was always saying crap. She was a parasite. I dropped her like a hot spud and ignored her.

AnswerThey will gaslight you and systematically undermine your confidence at every turn. By the time they are finished with you, you won't even be sure about your own name.
