INFJs have a need to live "romantic" lives, whether or not they are involved in an intimate relationship.  I've seen INFJs commonly characterized as being "Romantic idealists."

ROMANTIC:
4 a : marked by the imaginative or emotional appeal of what is heroic, adventurous, remote, mysterious, or idealized

INFJs yearn for romance.  They dream of creating harmonious, even caring personal relations, and they have a unique talent for helping people get along with each other and work together for the good of all. Such interpersonal harmony might be a romantic ideal, but then INFJs are incurable romantics who prefer to focus on what might be, rather than what is. 

The real, practical world is only a starting place for INFJs; they believe that life is filled with possibilities waiting to be realized, rich with meanings calling out to be understood. This idea of a mystical or spiritual dimension to life, the "not visible" or the "not yet" that can only be known through intuition or by a leap of faith, is far more important to INFJs than the world of material things -- although bringing visions to reality always plays some part in their aspirations.  As they grow older and move toward mid-life, the need to "walk the talk" and have congruence around making fantasy reality becomes more and more of a driving force.
