MBTI relationship

INFJ: A complex, intellectually challenging relationship.

INFJs take almost nothing at face value, and this tendency extends to their relationships. These ceaselessly analytical individuals thrive in partnerships where their perceptions are constantly being challenged and their worldviews are consistently being rearranged. To an INFJ, a satisfying relationship is one that offers practical stability but mental exploration and adventure. The intellectual realm is where the INFJ naturally shines. When they pair themselves up with a partner who brings this side out of them, they thrive.

INTJ: A stable, intellectual relationship.

INTJs crave security in the physical realm but boundless exploration in the mental realm. When this type invests in someone, they are bonded to them, and they are best paired with a partner who can make the same commitment to them. This allows the INTJ the opportunity to relax into the partnership and share the whole of themselves with their partner. This type is best matched with someone who shares their thirst for philosophy, literature and theoretical speculation. Being deeply, intellectually understood is the greatest aphrodisiac for this type. They thrive in relationships that hinge upon a mental connection.
