But in a romantic relationship? Being around/with another INFJ 24/7?? Ug. I think it would be boring, not to mention annoying (I mean, the same sorts of pitfalls/weaknesses/dilemmas/patterns for both), and wouldn't yield many opportunities to grow and expand as a person - on both of our parts.
I am going on 4 weeks with an INFJ (and I am an INFJ too). Things just keep getting better. The level of communication is amazing. Both of us value that very much. We are very very similar where it counts yet uniquely different in many of the important ways too. She just turned 40 and I am 41... almost 42. I think by this age INFJ's have worked out enough stuff in their heads to know what they really want and need. I other words it takes us a while to grow up but once we have it can be quite amazing with another INFJ.

I think it could work if you want someone truly similar to you. Some days I think I would like a girl with opposite personality traits, but compliment mine at the same time. And then there are days where I just would rather have that familiarity. I've spent my life around too many SF's, ST's, and NT's and I've never had an NF friend or relationship. When it comes to romance I think I would test it out with an INFJ chick. I don't think too much damage could come out of that, lol.
I just started becoming friends with a fellow INFJ woman. We were introduced over a year ago and probably nothing would have come of it except that she had a specific thing she thought I could help her with, and that got us talking. When we both found out we were INFJs, we practically jumped up and threw ourselves at each other. We're in a workplace saturated with NTs. I must say, it's very very nice to be among your own kind. I imagine it would be great with the opposite sex, too, with the caveat that you had better be ready for a Capital R Relationship, because it almost can't be anything else. To me, that's excellent for a female friendship -- I want to build a relationship and know she does, too -- but with men and women, sometimes that's a little much all at once.
