Another quote from Linda in the Larry King interview:
Larry King: Why did you break up?
Linda Thompson: Well, after four-and-a-half years of the yo-yo back and forth of other women, up all night, sleeping all day, the drug abuse, you know, it was... I just realized that I probably was never gonna be able to help him the way I wanted to help him. There was no Betty Ford Center then. There was no place for him to go, and he kept falling back into this prescription drug dilemma.
Larry King: So what did you do? How did you handle it?
Linda Thompson: He helped me actually. Because I was in San Francisco with him and he said, honey, would you like to fly back to Memphis? I have brought the Jet Star in to take you back. And, you know, deducing that he was not going to bring the plane in just for me, I figured he brought another girl in from Memphis, and that was his way of saying, you know, there's another girl here, but you know, you want to go back to Memphis for a few days. He was playing the Cow Palace. And I said yes, that's fine. I'll go back to Memphis, but I'm sure you've brought someone else to be with. Oh, no, honey, I would never do that. The last time I saw him alive he looked me in the eye and said, I want you to know something, honey, before you leave. No matter what you ever hear, no matter what everybody ever tells you, I just want you to know that I love you. I don't love anyone else. There's no other girl here, and you're the one I love. OK.
Larry King: Did you think there was a girl there?
Linda Thompson: I knew there was. She was on the floor below, waiting.
