What
part of you do you want to be understood exactly? You seem to talk about your Ne/Ni, but a type isn't only about the creative.
Duals definitely don't work like you at all, so as far as understanding what for example Se-Polr or Ne-creative feels like, well, I don't think that LSE can really empathize or comprehend. Duals are
complimentary opposites; the point of that relationship is not to 'understand' one another, but to support, accept and appreciate someone unconditionally, to feel secure and to have 'basic functioning' expectations being met, and that is worth one's weight in gold in close relationships imo.
But as said above, there are advantages to other relationships also. It's a balance. Are you ready to sacrifice comfort and security(no one to protect you against Se) for understanding, growth and work on your creative/demonstrative? Then semi-duality can be nice for example. If you're ready to sacrifice some of your basic expectations(no suggestive) and not being accepted unconditionally(mirage view each other as silly) in order to gain self-growth, self-awareness and more comprehension? Then mirage is pretty nice. If you're ok with less comfort(no protection of Polr, different life rythms)and less aligned priorities(rational/irrational ) in exchange for more fun action & outward orientation, then activity is nice too!
About activity: LSE seem to superficially deal with Si & Fi stuff the same way I do, but this kind of 'kinship' feels more like we commiserate together rather than support each other. SLI & EII have inert Fi so their Fi feels more like 'I'm doing my duty by being there for you' rather than 'I'm doing a U-turn in my personal affections because I feel like something's wrong' like LSE and IEE might do. Having the
inert pendant to your
contact creative seems to give it an achor and stabilize it.
My 2 cents
