I once read an account of when Zelda, along with F. Scott Fitzgerald first met Hemingway. Fitzgerald and Hemingway were already friends.
After a while, Zelda told F. Scott that Hemingway was a phony. Then Hemingway whispered to Fitzgerald that Zelda was insane. The writer said “both of them were probably correct”.
Yes, Zelda disliked Hemingway and Hemingway disliked Zelda. He eviserates both Zelda and F. Scott Fitzgerald in “A Moveable Feast” as well as Gertrude and Alice. Despite that, it is a beautiful book (a love letter to his first wife, Hadley) and one of my very favorites.
