Honestly I think INFJs do well with NT rationals but many will totally suck at emotional support and expression (esp intps) but overall INFJs have a enough grace to be ok with that. I think the big problem is S types. I just dont see how INFJs can be ok with S types, Relationships with ISFJ the (most common type around) are rough for me and I am surrounded by them!! these types while appealing to infjs due to there warmth and love of harmony are simply TOO DAMN traditional for fulfilling love IMO. they are great as family and friends and will feed you and remind you to eat. But man ...deep convos are just not there.
