I think this is a good pairing as long as both open up. Otherwise ENFJs could be 'offended' by Ne and Fi. I think ENFJs often really can't stand much curiosity and are a little afraid others could find out things they are ashamed of. So then they think of lame excuses because I act too much like a psychologist and if I show my emotions they think they're shallow.
ENFJs who don't open up are often drawn to ESTJs because they never make them feel uncomfortable. They won't talk much about their emotions then though.
But in general it's a good pairing because ENFJs help INFP become more outgoing and dependable, and INFPs help ENFJ become more independent and carefree. AND they can talk about their emotions easily.
