This situation I'm in now is very different for me too -- (in typical ISTJ fashion) I usually get to know (*cough*borderline interrogate*cough*...joke, kind of) a person for a great deal of time first, then access whether they have the qualities I'm looking for, then decide to proceed and try to figure out how to get their attention (and it usually fails because we're not on the same page). I basically would have a checklist and if they fulfilled all of that, I would proceed in my interactions with them.
But with this ENFJ, I've done none of that at all. I'm getting to know him in a very natural and fun way; it's comfortable. And I feel like we're connecting: like when i'm looking at him, he's looking at me in the same way. The whole thing is very odd for me - I'll be interested in seeing how it develops.
