Robert Zaller, the editor of 'A Casebook on Anais Nin' (1974), discusses his and his wife Lili Bita's friendship with Anais Nin, which was, as he put it, "...uniformly positive. Anais was an extraordinarily generous person. Faithfulness in the conventional sense was not important to her, loyalty was. She was too intelligent and too mercurial to ever be satisfied by anyone, and to that--to herself--she was indeed faithful."
