I'd have to say from personal experience that I don't think an INFP is a good match for an INTJ.
My entire time with him he was trying to 'fix' me and was very judgmental and rude when I put my foot down. He pretty much abandoned me when he realized I didn't see myself as broken for not being emotionally needy, nor did I care to cater to what his ideas of what a woman should be. He was a rather evil fellow too, manipulative and selfish when I had already gone far out of my way to make things work on my end. I remember him stating that he felt that I threatened his manhood.
I really don't understand NFs nor do I like them. Then again every NF I've met has been a repulsive human being, so I may be biased here.
