Hm, that's very interesting. I do agree with the notion that nothing, absolutely nothing, can give you what another human can (in terms of connection/intimacy/emotion etc), but I feel like my Enneagram type (4w5) can affect the whole "approach to people" thing. My whole life I've never really been "chosen" or had people be interested much in me, so I believe that has affected me in the sense that I don't like to be the one to go after people, or a person. But when they do come into my sphere, then I think that's a different story. I remember one of my closest friends, at the beginning of our friendship, being like "why are you so interested in me", cause I remember I would drill question after question around things like personality and just kind of became obsessed with getting to their core, or just really getting to know them (which for me, I thought that was just normal, nothing out of the ordinary), but I get most people wait, or are slow to get out of the "how are you?... oh great" phase, which I despise, I hate dry conversations or beating around the bush, although I would painfully go through that if I don't feel like I'm close enough with someone to get to be deep. So yeah, I'm confused, cause everything but that extroverted crap I relate to.
Also, I have no interest in "people" as a whole. Like sure, it's nice to be around others, like to feel the energy of other people existing around you, but like I'm really bad at the whole group thing. And it feels more lonely to me to just have a lot of friends around you but no closeness... so I don't know. I have considered before being a so/sx instead, but I feel a bit wary of that cause of the whole being "ungrounded" and "head in the clouds / airy vibe" description.
