Margaret Mitchell said this quote

“ He would never be any different and now Scarlett realize the truth and accepted it without emotion—that until he died Gerald would always be waiting for Ellen, always listening for her. Her was in some dim borderline country where time was standing still and Ellen was always in the next room. The mainspring of his existence was taken away when she died and with it has gone his bounding assurance, his impudence and his restless vitality. Ellen was the audience before which the blustering drama of Gerald O'Hara had been played Now the curtain had been rung down forever, the footlights dimmed and the audience suddenly vanished, while the stunned old actor remained on his empty stage, waiting for his cues. ”
