You're probably ILE-Ti, hence less valuing of Ne/Si and more focus on Ti/Fe. You said yourself that Ti-creative and EP temperament are OK typings for you, and there's no way you're SLE; you're way too ambiguous. So what EP Ti-creative type is left?
isn't necessarily someone trying to take care of you directly. It could be someone knowing when you need a backrub, and just the right spots to work on. Someone cleaning up the mess left behind while you're too busy in your own head to care about such tedious things. Someone making an aesthetically-pleasing environment to help calm your restless mind. Someone making sure you don't pass out from low blood sugar when you get caught up in a random flurry of activity. Someone just being patient and gentle with you.
Have you read about cognitive styles at all?

You focus a lot on contradictions, and seem unable to resolve them on your own, as others have mentioned. SEI has a Dialectical-Algorithmic cognitive style, one that supposedly deals well with contradictions and paradoxes. Can you see how that type of style may be complementary to your own? Surely Socionics has its own contradictions, but you're contradicting yourself in general.
Did you grow up with any SEI family members or friends?
