I think as an INFJ, the NF hopes to accommodate all personality types, as means to keep the peace. However, my experience with other INFJs has not been the best. We communicate well with one another but I become bored fairly easy with those relationships. I've found myself in relationships most often with ESTP's and we get along extremely well but it lacks a deepness. So far my experience with ENTPs, little as it is, has been phenomenal! I've met 3 and we just click! I am fascinated by their enthusiasm and intellect. Very, very easy to talk to and they challenge me which I enjoy. But my opinion is subjective of course. Friendship wise I find myself most often befriending ENFPs. They help me to not be so introverted.
