I don't know many INFps in real life actually the most I know I met on the personality forums and so I have a pretty good understanding of this type. It's the rarest type so I can't complain. I like INFps online and I had one friend in my teenage that I tentatively typed INFp afterward.
One of my last crushes was an IEI . Perhaps it was a persistent attempt for us both to make it work and the only thing for sure is a mutual curiosity and the want to make it work. I am not certain our failure to communicate in the happiest ways is caused by Fi and Fe clash and that's why it makes so much sense to see if that's also what others have experienced.
He said it was hard to read me and know what I feel. I felt sad and disarmed by his need to hear words and statements and not being able to see through me. He said I tried too hard to hide behind ambiguity and nebulous meanings. I thought he didn't realize how unrefined it can be and how much he kills otherwise. He accused me of being too peaceful and trying to get along with many people and hearing many sides. I felt he was fake for the sake of having a good time in the moment or for other more interested base reasons and not for the good of a relationship or because he cared about where someone is coming from. He said I was selfish and narcissistic. I found him the same although about different things. I don't want to go on and on . I'm open to give details if anyone is interested. Before that let me know if Fe and Fi relationships are doomed (even if between NF s ....) and we should all only look for duals and activity partners .
