Priscilla and Elvis's marriage, in "Priscilla," is rarely "good." While she is pregnant, he tries to leave her before changing his mind, and she is often alone with Lisa Marie. Priscilla describes the same scenes in her memoir and says Elvis didn't want to have sex with her after she gave birth.
In the years after their wedding, Elvis spent more and more time away from Priscilla and Lisa Marie. When Elvis began his Vegas residency, Lisa Marie was only there sporadically, and she saw lots of evidence that he had other women around, like letters to their house in Palm Springs from women who'd been there.
In her memoir, she describes one night when, angry because she had revealed her own affair to him, he has Priscilla come to his suite and, in her words, "forcefully made love to me." In "Priscilla," in that moment Elvis is violent, but does not rape her. In years since, when asked about this incident, Priscilla has not commented and directed people to the book.
