True Detective - Rust Cohle | Mr kitty (After Dark) 

This. ^ he never had any romantic feelings for anyone, focused on his work, broken inside, pessimistic

Rust is not broken. He has the most clarity among all the characters.

Rust is actually a romantic, but he doesn't show it outwardly. Remember that he lost his daughter, maybe everything went to sht after he lost his daughter.
