I'm an ISTj and I've met (and fallen for my super-ego, INFj). I find her very physically attractive but I can't seem to melt her the way I'm capable of with other girls, especially ExFx. I feel as if we have nothing in common and nothing to say to each other. When I do say something funny or use my dry humour she just seems to smile. I get no feed back. On this point I can see why the ENFj 'drama queen' is my dual. I have no idea if she actually likes me or if she's totally indifferent, I just get that half-smile. And this undermines my confidence so I increasingly say less funny things and I come across increasingly stiff and boring (the way people who don't know ISTjs very well can think). I feel if I met her for lunch or something like that we'd just be eating in silent, that the conversation wouldn't even carry us 5 minutes. I feel so frustrated because I do care for her but feel our personalities will keep us apart. Is there anything I can do to mitigate super ego relations? Or do i just simply have to bite the bullet and move on?
