I wouldn't say I'm "fed up" with any function, more the misuse of said functions, being an Fe user, I've done it myself. With INFJs, I just sort of see them for what they are now and they aren't very attractive to me in terms of sharing my life with them or being emotionally invested. I like INFJs but feel INFJs are best when they focus on humanity and not personal relationships as they struggle so much with them and maybe in part people struggle to recognize the value in what INFJs can potentially offer.
I would agree with the not listening to what they say thing, my best dating advice if anybody chooses to go down this path with an INFJ is as follows:
1) INFJs are the least satisfied of all the types in romantic relationships this has nothing to do with their partners however so don't take it personal, just know that know matter who you are or what you do it will be the case.
2) INFJs are extremely prone to cheating and swear it isn't so which paradoxically is why it is so.
3) I highly doubt you will ever actually know the INFJ, they keep a lot to themselves, here's a prime example:
"Around 1666, Isaac Newton locked himself in his room for a while and, basically, invented calculus. But despite the enormous importance of this invention, for some reason, Newton didn’t tell anyone about it for years afterwards. He mentioned some of the basics in an annotation to a footnote somewhere, and actually used calculus in his major physics works, but never published the original paper on calculus itself. A few years later, a man named Gottfried Wilhelm Leibniz also invented calculus, completely independently of Newton’s work. Newton got fairly upset about this, accusing Leibniz of plagiarizing from, well, the papers that he had failed to show anybody."
This is pretty classic INFJ behavior, lock themselves in a room, invent some important world changing shit, never mention it, get pissed when you don't acknowledge the accomplishment they never mentioned... to anybody... ever.
4) If you feel ANY push/pull from them, run, don't walk, run!
5) They will pull you in quickly with their desire to connect (Fe), once you're in pretty deeply, they will realize they're vulnerable and distance themselves (push/pull), if this happens, end things.
6) I would not have sex with an INFJ for at least 3 months, seriously, they aren't made for it, get past
#5 first and see what's there, proceed accordingly.
