My fiance is an ESFJ to the max (I just tested him. He's never taken a personality test and I was always very curious).
We work out pretty well, because even though we handle things IN THE COMPLETE OPPOSITE MANNER, we still have a lot of hobbies and interests in common. One that that always bugged me, though, was that he tends to be more quiet and slow when expressing his opinion on certain things, and sometimes, I feel like he's just shutting me out. We've established, however, that he isn't used to being pressed for information and doesn't remember that I feel hurt when he isn't open to sharing, and that...well, I'm impatient and nosy.
