At least back in Minnesota, a long while ago, I always sensed there was this odd dynamic where neither of us quite knew what to do with the other, maybe a 'waiting game' on both of our parts. At one point I became interested in dating him, but as those things go I then met someone else. And he never initiated anything with me, so I assumed that he wasn't interested (perhaps rightly so? I tend to think extroverts especially will just ask someone out if they're interested).
Blah, this isn't going anywhere! haha.
To the OP/title of the thread -- while I think many types can work out just fine together, I will admit that for myself I'm coming to realize how 'necessary' an Ne complement might be for me. NiTi just bogs me down in an internal world, where I come to see so many possibilities that I become immobile and sort of Defeatist. Ne provides a necessary 'awakening', and refreshing viewpoint (Ne seems more optimistic by nature), brainstorming options, more concretely externalizing things. Definitely pulls me out of myself, and provides a perspective that gives me more clarity - and hope.
