Wait, are you talking about yourself in third-person...?My long-term is an ISFP. We have a standing deal that we're technically friends, but we used to technically be in a relationship. While technically being in a relationship with each other, we rented a place together. We still live here. And we're friends. But we're romantic friends. Long-term romantic friendship. The friend thing has released a lot of pressure, and we are awesome together. The reason for the friend thing is both of our plans for the future that are the exact opposite of each other. ISFP wants marriage and kids and boring life. INTJ wants freedom and fun life. ISFP is also quite conservative. The kind of conservative that's native to the middle east. When I say quite I mean a little. Not a lot. But enough so that INTJ feels a little pressured when it comes to attire around ISFP's friends. That doesn't count anymore because INTJ and ISFP are just friends, and friends can wear whatever the fuck they want, without it being embarrassing for ISFP. Also, whenever ISFP goes ahead and finds some random person willing to marry and breed, INTJ can be happy for ISFP and remain friends. If we were still in a relationship, then it would just be sad when it came to that.
Heh, I usually imagine other types pegging us for nitpicky.ISFJ and it was terrible, but probably not totally due to being an ISFJ/INTJ pairing. He was just not really a very nice person and I was willing to take that at the time (late teens/early 20s). I did view him as being extremely nitpicky though. Not sure if that's a common view of ISFJs from an INTJ perspective.
