Relationship between type 4 and type 3

The artist and the chameleon

Éponine (Les Misérables)
Jay Gatsby (The Great Gatsby)

Attraction

It is a relationship that can be very complementary if both manage their compulsions.
The 4 is attracted by the self-confidence, charisma, sociability, energy, diplomacy and winning personality of the 3.
The 3 is attracted by the sensibility, the sentimental depth, the anthenticity, the mysteriousness and the romanticism of the 4.
The 4 can help the 3 to pay more attention to his inner feelings that he represses, while the 3 can help the 4 to be more organized in his projects to advance towards his dreams

Points where to be careful

The 4 is very sensitive, whimsical, needs proximity, and can very badly live the negligence that the 3 can have on his relationship by focusing on his professional goals.
The 4 may feel that the 3 pays too much attention to his image and career, flees his feelings, and is too superficial.
The 3 can feel the 4 as being too whimsical, in too much need of attention, passive, unproductive and ineffective.
