Personally, I do relate to the OP. Granted, maybe the formulation was a bit rough around the edges, but I personally do look for deep meaningful connections. It's what makes me feel alive. This automaticall makes me friendly towards just about anyone that approaches me, because they hold potential (depending on the circumstances in which I meet them). This is even more true for people that I myself approach, as I saw something in them that I like.
However, not every person is compatible with me and I am fully aware of that. Does that mean I don't care for them? No...but the great start we made stagnates, strands on a certain level, which means it is nice to talk to them, but it stays superficial, is not really that intense or meaningful to me. For some however, this level already apparently feels intense, as they themselves don't naturally make these connections with others. And that can create confusion. Especially as there are only 24 hours in a day, and it is hard to keep up with everyone and still get time to recharge. I'm not as skilled at this as, say, an ENFJ.
Does that mean I don't like these people that I sometimes don't have time for? Not at all. But it can also means that they might consider us to be more than we are. I personally just always wish for them to enjoy what we have, I do the same
As for SK's question...the moment we truly click, yo uwill notice it in the convo's. They are deeper, and ask about who you are. I always do this anyways in the beginning, but if there's a lot of common ground or interesting stuff to work with, the convo will flow. If it stays with silly banter, and doesnt reach that personal level...we're just having some fun. People I'm truly close to also get to see bits and pieces of who I am. Meaning...I do share who I am, but I won't share my vulnerabilities with just anyone, unless I'm under great duress. I'll share stuff I'm not proud of, things that I feel uncertain about, things from my past. One exception: if I have an experience that I've digested and think might help you with your current situation, I'll openly talk about it. Though that too indicates more of a bond than just silly goofing around, it's not what I'm talking about.
I'm talking about the things that i truly feel scared of showing, due to judgement, and the fact that it is in fact a sensitive topic to me still, something I'm still working on.
If I do that..you at least have part of my trust. The amount that I share, and show, indicates how intense our bond is to me, and how much I trust you, and feel safe with you. You'll also see an increase of me seeking you out. I tend to let people come to me, unless I 'm in a silly mood and wanna prod some people. But, the moment I just wanna hang out with you, even when we have nothing to say, just to enjoy your presence...that means something

Even if I sometimes disappear for a while, or don't seek you out (I'm probably off being distracted).
