All of these are really excellent points Eye of the Potato. All of what you mentioned do go through my mind recurrently, and sure it is ENTIRELY possible that i am EII.
I'm not sure if it's my attraction to a couple of Te-SLIs that clinched my choice of IEE so much. As a newb to socionics a couple of years ago, coming from the MBTI world, I was convinced that I was an introvert. I mistakenly typed myself IEI at the time (wow, really bad mistake!!!). I also felt that I'd experienced duality with the one Te-SLI, which is why i got more interested in socionics, so that was really the one thing that I was more or less sure about. He seemed a lot more sociable than me, so i actually typed him SLE at the time (

).
Upon further study of socionics (in various ways, including reading, interacting with forum members, and just trying to understand the concepts), it became obvious that i was most certainly not beta, my dual was DEFINITELY not SLE, and i seem to function more as a socionics extratim in that i have a drive to interact and influence objects/peoople, as opposed to just taking in and assessing objects/people. I have really done some really blatantly obvious things to make my feelings for someone known (including these days with another Te-SLI). One thing that sort of has restrained me in the past with making really obvious moves, has been the influence of my mom, who had basically raised me with the idea that a guy is supposed to make all the moves (she's SEI) and the girl is supposed to be demure and "hard to get". She constantly talks about that sort of thing, and gives examples, etc, and makes fun of situations that go against that. So that had been my approach in the past, except when my drive to initiate got soo bad that i would be like "screw it, i'm going over and talking to him" or write an email confessing my feelings (did that twice).
Anyway, one of the things that clinched my identifying with the IEE type was also Rick's Extended IEE description, which was totally spot on in every way. I also VI a lot like a bunch of Fi-IEEs.
However, I definitely have not ruled out EII, but either way that still wouldn't be too far off, i'd still be delta NF. And I generally find both LSEs and SLIs appealing (of course case by case basis). Activity is a great intertype as well, I wouldn't mind ending up with one at all.
