What do you mean by "get?" I think having someone who's a complete opposite could be exciting for an ISTP (at least for awhile), but what is in it for the ENFJ?
It's supremely difficult to describe the sort of kismet I've experienced with certain ISTPs. I shall attempt it at any rate...
My best friend for years was a male ISTP and we hardly ever fought. When we did fall out, it felt so bad that we'd both be a wreck and would get the disagreement over with as fast as humanly possible. We'd talk about literally everything from politics to religion to books, hot rod cars and race together, he wasn't even remotely afraid of me and my Fe volcano. He'd write me notes and leave them under the wipers of my car when we weren't together. I'd steal his car and go to lunch. He didn't care. He willed her to me, in fact, and she was his prized possession. She meant the same thing to me as she did to him. He was there to scrape me off the ceiling and hold on to me until I got calm when being hideously sick and in pain finally drove me to the breaking point. Things like that. It was grounding and it was safe. He'd walk through fire for me, mostly because he knew I'd never ask him to. It was a relief to not be treated like a ticking time bomb.
I was in a relationship with an IsTP, was deeply in love with him and it was mutual, but he was a drug addict. End of story, I guess.
It's not every ISTP (though I get along with 99% of them). I tend to fall in with the "high neurotics" -- strong Ti and extremely assertive (and frequently punishing) tertiary Ni.
I also find communicating with ENFJs difficult, but then it could just be my sister...
A word to the wise:
Never use your family members as a template or base for judgment in romantic relationships.
I personally don't need anyone to calm me down. I need someone to roll with me.
Oh how I need that...
I've had some positive experiences with just a few INTP males (and about a million of the girls I'd love to be boys!) and they were all married. *shrug* That's no good. The one INTP bf I had was a disaster because he was a severe control freak, extremely jealous and condescended to me on a regular basis. He criticized me so much I felt ugly around him. That, to me, is a personal problem, not a whole type problem. I have difficulty warming up to the general anti-social bent they have too. ENTPs, even when maladjusted, are social animals, and I feel more relaxed around them.
Not to say that I haven't felt a strong pull towards INTPs before because I have. Ti-primaries (and Ne-Ti for the ENTPs) is incredibly attractive to me.
I think you just need someone that can put you in your place.
.... KIDDING!!! *quickly runs off*
You wanna go, big boy?? *slaps hands together* C'mere! Lemme hug your neck!
