Jared Andrukanis, quoted from Bourdain: The Definitive Oral Biography in Vanity Fair:
He put a lot of everything in that basket–he shoveled his work life, his personal life, he shoveled his persona into his relationship, and that is a recipe for fucking disaster, no matter who you are.
“That basket” being his relationship with Asia Argento, for whom he appeared to be limerent right up to his tragic end.
