I think INFJ internet representation is all over the place...Its hard to narrow down the mbti type INFJ into somewhat clear traits and structures, especially because its hard to read them and they are manipulators in a way that they act in a certain way mainly in order to avoid conflict.
However, it's very interesting to see what happens if they don't do that.
If an INFJ stops masking, this can have several reasons: extreme stress (which comes easily for them because even slight changes or small interactions takes a high amount of emotional energy of them), being with people for too long, mental illness, or the rare case that you are even so uninteresting to the INFJ that they don't even bother being friendly to you or in the other case that they like and trust you so much that they stop masking.
Because deep inside, INFJs are rather bitter about the world. The stressful trait to notice a lot of small things makes them see often enough that the effort to be good is either too small to make a change or doesn't get repayed. They try hard to be good because they think how others feel is more important than how they feel themselves, but especially under stress, they can seem dry, bored, not caring, when deep inside, they still care a lot and just cant show it in the moment. INFJs have a very misunderstanding trait that makes them share only a part of what's going on in their head, mainly because its a labyrinth there and they also kinda think that a lot of stuff is just obvious to others when it's not. This creates small conflict that INFJs normally try to avoid: a circle is created, a loop the INFJ has a hard time to escape.
So when all their energy for empathy left their body, an INFJ can in fact get quite cold, or at least seem like that. They also can get sad, depressed, anxious, but won't show it, only to those they are closest too. But it's important to know that something like that could be going on when you interact with an INFJ. They often seem to have a lot of fun and be happy and loving, but as soon as they start disappearing, say they are 'stressed' or their answers get weird or unemotional and somehow off, they may be stuck in their loop and need help they won't ask for.
INFJs are caring people, but often don't get back the amount of love they give. They wonder why this is like that, and think they are weird or bad or unlovable people, and every little misunderstanding manifests these thoughts. If you want to do something good for them, be patient, ask them what's up, be there without judging. When an INFJ thinks they did too many things 'wrong' in an interpersonal way, they will withdraw too and wait for more signs of the other side.
