Tjose 2 kids came from a veru non affectionate home so they clung together. I don't think they were having sex. But richard was controlling like his mother and he took over Karens life. I amsure he wanted to keeo the money rolling in and I am sure he said mean and hateful things to her. I rad that his mother used to give them all kinds of pills. Valium,sleeping pills whatever so I see where his drug problem came from. I wish her ex husband would write a book and tell what he saw. He was distraught over her death and angry and there had to be things he saw that would shed lite on her anorexia and bullimia?
