Only thing I don't really get is the strong sense of obligation and need to fulfill invisible "duties" to a person that come with such a connection. I think that might have come from having too many ISFJs (or maybe just SJs in general) in your life as your only positive role models.
I have noticed a strange tendency within myself, though. I find I really only like interacting with people when we're first meeting and realizing how much we connect, enthusiastically discussing/analyzing something intellectual in depth, or one of us is trying to comfort the other's emotional pain. I find that anything else tends to bore and tire me quickly.
Which creates a pattern in which I get really close to people emotionally at first, enjoy it as long as I can, and then (often unconsciously) distance myself when I've gotten as much emotional/intellectual stimulation I could out of it. Then, I find myself just forgetting about the person entirely unless I happen to see them again... and then I'm extremely uncomfortable interacting with them again (because they're too far in the past for me at that point), so I just don't usually. I'm not entirely sure this is a good thing (especially since I'm somewhat unhealthy in many ways anyway), but I never really thought about it until now.
I don't usually perceive obligations unless they're expressly stated, and I have a tendency to construe an obligation I don't like as being the other persons fault, and might end up disliking them because of it. I very much don't like seeing other people feel obligated in a personal way, and do what I can to prevent them from feeling that way.
I wonder what all of this means?
