I've dated quite a few SP's & have a possible SP boyfriend on my hands now (though, who knows!)
I know the assumption is that an N with an S would lack any sort of deep connection, but I think that's where MBTI generalizes a bit.
I've always been able to have a connection with the SPs I've dated. It's not like they are so incredibly practical that they can't handle any sort of theory. It's like saying that I, as an NF, have absolutely no common sense & can't get outside of my head because I'm an N. It's simply not true.
Also, there are ways to connect with another human outside of abstract theory. I find my favorite connection I have with my boyfriend is that we both enjoy physical activities & traveling. He's also very thoughtful and a secret romantic.
He sees my needs and fills them the best he can & I do the same for him. I don't care what type he is... it works just fine for us.
He seems to border on the S/N line, but I am still much more theoretical than him (one of his biggest complaints is that I am constantly reading between the lines). If I feel the need to sit and discuss something philosophical all night long, I have other friends. I don't need it from a relationship.
The living in the moment as compared to not living in the moment was a source of frustration at times, but you either work with it or stay stubborn & let the relationship be ruined. If anything, dating SP's has allowed me to relax a bit and I think I've in turn brought some sort of order & structure to their lives. ESTP's & ISTP's do tend to differ from the traditional SP approach to life, too - I believe both of their interaction styles actually favor more of a plan ahead sort of approach. I've never had problems interacting with either of these types. Anyway, just because a person prefers to live in the moment, doesn't mean they will be so in the moment that cheating or outright dropping you will occur in your relationship. Figure out what a person's values are and you'll find that ANY type who doesn't value the meaning of a relationship will do things like cheat and drop off the face of the planet. It's not necessarily an SP kind of thing.
Honestly? What makes a relationship is how you treat one another, trust, honesty, and communication. If you can make that work with someone, then it really doesn't matter their type.
Personally? I have the most problems with NTPs - the supposingly perfect fit for an NF.
