That flip of the E/I seems to bode badly for relationships. I was married to an INFP. It was a nightmare on wheels. We had a lot in common but I could never reach the depths of her emotions and she was always complaining that I 'invalidated her perspective' because she would express emotions about situations that were strong and deep I couldn't relate at all, and as we were married, we had to deal with these situations in some kind of compromising way, but that was impossible, because to compromise meant she had to deny the depth of her feeling about something, and I would have to accept her (to my mind) overly-extreme feeling about it. It wasn't enough to simply acknowledge to her that I understood she was feeling this thing, I had to accept that her feeling about it was the right one, and act accordingly. Usually this meant ending friendships that I didn't want to end. She would 'pick up' on some aspect of the friendship that triggered a strong emotion and as a couple we could no longer be friends with that person. I had to endure her anger if I wanted to continue the friendship. This happened repeatedly. Her phrase was 'I have alarm bells about so-and-so.'
Anyone else been in a bad INFP/ENFP match?
