Jack Dawson's Lover Type is Wave

Titanic. The Free-Spirited Lover.

Jack Dawson lives by instinct, reading Rose in a single glance and knowing exactly when to make her laugh or let her breathe. That easy intuition, paired with a life built on no fixed plans, is peak Wave energy. He owns nothing but a sketchbook and his own freedom, yet he loves without hesitation or condition, adapting to her world at dinner or hers to his without losing himself.
