Bump!
Hey INFPs

I have a question, and it might be too vague to answer, and I apologize for that in advance.
I have a few INFP friends -- though not many -- and I've never really gotten close with any of them. Here's what has almost always happened: they open up to me (a lot!), I listen patiently and gradually define my friendship with them as more of an older- and younger-sibling relationship (not on equal terms), and then when I finally decide to open up to them (just a little!), they get awkward, so I never open up to them again, and they never bring up the exchange again, and it's as if I never opened up to them in the first place. I'm posting here because I have no idea what that's all about!
It's happened both irl and on the forum, with INFPs. I'll open up in the typical ESTJ style of making oneself vulnerable (i.e. explaining feelings in a very straightforward and deliberate style, 99% devoid of a sense of humor). I'm guessing that it comes across as intense because they're so used to thinking of me as oh so confident, so together, the level-headed one, the one who is so organized when they're so Ne-style disorganized, etc -- and they don't stop to think that maybe there's more to me than that.
But what I don't understand is: wouldn't INFPs know better than anyone, what to look for in a slow-but-sure Fi reveal? If the INFPs in my life are Fours (and I know a few of them are), wouldn't they know better than anyone that Everyone Has Their Eccentricities That They Hide From Most People Because Most People Don't Understand? :uni:
Even the ENFPs I've met have been more understanding when I open up (in general), because at the very least they give the "I've been in a similar situation" Fi-comfort response... whereas what I've mostly gotten from INFPs has been "... oh." or "... ahahaha... um..." or "really??" <-- That one really killed me. That was when I was actually showing Fi to them, i.e. showing them a value of mine that I don't consider to be very rational, but that I hold anyway, against my will.* You'd think of all people, an Fi would know not to do that?
So, like I said, this question is vague and confusing, because it might not just be with INFPs (and might be with other types too), it might be more to do with ESTJ-ness than INFP-ness, and it could have more to do with maturity than the Myers-Briggs. It could also be the Enneagram? though I'm not sure about that either. I'm confused enough about the issue that I can't narrow it down without input -- and INFP input would be perfect.
Thoughts?
*ESTJ fact no. 16745: Ambiguity scares us. Values are inherently ambiguous. No matter how dogmatic an ESTJ is, it is guaranteed that, deep inside, they all share that same fear. But we have to live by our values, even though we know they're full of holes and impossible to argue rationally. So if we show our Fi, it's either in a very controlled environment where we know we'll be beyond criticism, or it's in an Fi explosion as a result of a continuous stress/anger buildup.
