I'm with ISTP, somewhat close to N/S border, and wouldn't recommend a similar pairing. Or, I'll wait and see.
The problems are similar to what you've said of INTP-ENTJ; Here, my ISTP is criticizing me (the ENTJ) on the perfectness of thought and accuracy, even on trivial items. ISTP like to point out mistakes and focus on errors, rather than focusing on performance, and how the errors actually matter on anything done or experienced.
She's easily discouraged, quite unaccommodating, to the point of not working well with many people. She does an attempt at compatibility by shutting down her criticism and speaking in a fake voice, but turns really caustic when she has decided on her opinion.
She's almost unable to do collaborative thinking; rather, she switches between being submissive servant and attempting to dominate, which fails. She's mad for me thinking about many things differently than her; my way is just "wrong", and I'm inconsiderate for having my "offensive" opinion. Not that matter what I *do*, or what *she* does, or does not.
FYI, my opinions are not that offensive really. She'd just wish them to be the same as her's, on many subjects.
She doesn't notice her anger, or other emotions.
And me?
I'm hurting her, as I'm rather straightforward, and although I try to be considerate, some times I just aren't. I'm prone to not giving her enough time to think through and finish everything she starts. I press her hard for her not valuing the time sufficiently. I'm often paradoxically unable to relax with her slow speed with most of the stuff, as I'm afraid of missing to everything I want to do.
As opposed, she doesn't have many plans. She's excited about getting some more education now, and she's done a lot to it, so It's not that she were totally lazy or anything.
Still, the different pace, and the wildly, completely different priorities for "working my own pace" and "getting things done", "doing" vs "thinking", etc.. make the life quite difficult.
I'm not sure if her financial difficulties stress her so as to make her act that way.
In any case, I want much improvement on our relationship.
I'm also disappointed in her often straightforward way of thinking, when she has thought to covered "everything important": she's not very inventive, but I can blame S for this. She complains a lot to me for not having some S details in my life in a most practical or aesthetic manner. But, these are both S issues. There are already enough reasons for trouble on our I/E and J/P differences.
I'm most disappointed at her for not really being actually practical with her thinking, i.e. making something work and getting some good things for herself. She's almost like idealistically inclined to impractical philosophies and ways of thinking, although she doesn't admit it. Yes, she's still ST and not NF. It's different in manner to NF ideology; her ideology follows from some desired truth, i.e. this would be good, if true, so this kind of thing must be forced, and things has to be done in accordance with this imagined, desirable view. Lack of N makes her unable to consider all the aspects tho, and lack of J makes her extremely undisciplined in double-checking all her ideas to see if they can actually be made into effect. Uhh.
