I dated an infp for 3 months a few years back. We bonded instantly and I was falling in love for sure, we spent most of our time at his place watching series, cooking and eating. After a while however it started to bother me a little that he never wanted to come out with me, like meet my friends, go for a walk etc. He always canceled last minute. Then out of nowhere he broke up with me, apparently he was feeling depressed and yada yada . Which i don't doubt.

But yeah, that was that, it was good while it lasted. I felt at home with him. But i don't know if it would have worked in the long run because he was so "low energy" and I'm pretty high energy as soon as i walk out the door. However it seems that his mental health issues was a big part of the problem for us.

I don't think loyality is an issue for enfps when they are in happy commited relationships. For me personally loyalty was only an issue in one relationship where I felt trapped because I was emotionally manipulated into staying.
