As with everything when it comes to INFJs, when it rains it really pours.
Isabel Myers (INFP) married a man named Chief, an ISTJ and a good man.
They were happy together, but according to Isabel's own type theory they weren't predicted to be perfect for each other.
So just remember: Ever since Keirsey published Please Understand Me II in 1998, it has generally been accepted that the Rationals are the best partners for the Idealists.
This appears to be true--at least from the Rational point of view.
Later on, Myers said that if she had known about type theory, she probably wouldn't have married Chief. There is a lesson to be learned here: type is not everything, nor should it be the decisive factor in choosing your lifemate. Then too, the connections between type, attraction, love and marriage haven't been well studied yet. Tieger and Baron-Tieger (2000) found that Idealist-Idealist pairings have an average satisfaction rate of 73%--the highest attraction rating for all the NF pairings, and almost the highest possible satisfaction for all pairings. Green = Guardian, Blue = Idealist, Purple = Artisan, and Teal = Rational.
