It is incredibly difficult to communicate with someone who is passive-aggressive because they shut down communication by insisting that everything is fine on the surface when it clearly isn’t.
Normally, this happens to the people with introversion, feeling and judgement traits specially when they have gone through some tragedy. So, IFJs are the people bearing this behavior more than any other personality type, right?
Im an infj Lol. I cpuld say that I am guilty of passive aggression. This is primarily because these personality types prefer harmony and expressing their thoughts may create a rift in relationships (atleast that's how I perceive it). But seeing as how passive aggressin destroyed my past relationship with someone I liked, I would say that it's a big no no. People should learn to communicate their thoughts in the most constructive way possible
