Sorry, dudes, if there's one ENFP trait I can't grasp, it's undying love for INTJs. If it's required that I go out and get one, I should probably just either stab myself in the head or change my type now.
LOL. I have an INTJ female friend IRL and we get along well.
I know other types who quickly got over being charmed by her, call her hypocritical, neurotic, superficial and have told her in no uncertain terms that they had better things to do.
I know this is over-used, but it seems like your ENFP is "immature" meaning still very much growing into herself and stuck on this anxiety loop of making sure people like her above all else. I remember that to me at a certain point in my life, censure, criticism, conflict were
unbearable. My neurons would practically pop out of my skull. So I trained myself to take it - I found out later this is a form of cognitive therapy, to literally desensitize you to something.
It's not that your root neuroses or whatnot change, it's just that you literally get so used to something that you no longer care. Perhaps the point of desensitizing is to tap out the adrenalin and other neurotransmitter processes when you are exposed to that stimuli (criticism, conflict) - basically short-circuiting evolutionary self-preservational mechanisms that no longer serve a purpose in this modern world.
Anyhow, as a fellow ENFP I do see the "mixed signals and somewhat confusing behavior" in myself. Also the spinning my wheels and doing anything possible to keep my mind off things and keeping things constantly in motion. It takes a minute for Fi to work itself out internally and me to feel safe and okay clearly expressing it to the world.
However, I do not condone lashing out to those closest to you or behaving irresponsibly towards others. I think that's cowardly, you do it because you don't have the guts to confront what is really bothering you in life. You should never hurt the people closest to you just because they are the easiest targets or you bank on the fact they are too invested or enamored of you to leave. I despise that and I lose respect for people when I see it. Get a handle on yourself and grow up.
I am much more likely to withdraw and just be alone until things are sorted out than act out.
I think other people who are charmed by ENFPs have a lot more patience for "ENFP bad behavior" than I do and more likely to chalk it up to the overwhelming and mercurial nature of Fi. I'm over it. I chalk up bad behavior to people not getting a handle on themselves and not
trying. If you at least make an honest effort in my eyes than I am very understanding, but if you don't even try I don't have much (any) sympathy or time for you.
And yes, this is very much rooted in feeling like "I've been where you've been" or "I'm where you are" - I have to deal with it, you do, too.
Every person and every type has a cross to bear but should you really be allowed to get away with more just because people like you most of the time or think you're a free spirit?
People do a disservice to one another by letting them off too easily. I am starting to feel like a lot of people in my life have let me get away with a lot (or really let me get away with doing nothing much at all) because they figure I am a "free spirit" and "that's just CzeCze" and they can tell I'm running from something and would not be amenable to what they have to say. The only person who really hounded me was an INTP friend but she has since given up.
That's why it's important for ENFPs to take it upon ourselves to do it for ourselves. A lot of times the lack of criticism in our lives isn't approval, it's people not taking us seriously, giving up, and letting us coast.
Then there are those who choose to stay around but I can see them carefully emotionally distancing themselves... Maybe it is a 'social skill' to know how to do that while maintaining a semblance of intimacy. Mouthing the right words, blowing the right kisses, etc.
You mean the ENFP is exhibiting that 'social skill' or other people who are distancing themselves?
And Mr. Teddy Bear you are saintly to put up with all this.

I'm sure your ENFP does appreciate the heck out of you even when she's not. I'm sure if you remind her then her window of focus will snap back on you and she'll realize the ways she can be flighty. Or she'll tell you she had no idea you felt like this because you always feel close to her heart.
