People married to people with “mental problems” often stay in the marriage hoping that something they do can somehow cure the person. First thing a family member said when he saw her on TV, was she has an “substance abuse” problem. He’s helped many get help. Think he could be right. Have not heard what the daughter have had to say, have you?
No, I haven’t directly listened to his daughter talk about their stepmom, Marianne. (The speakers on my computer will not work for me. Oddly, though, they work for everyone else!)
What they are quoted as saying, is that their dad and stepmom did not have an open marriage. That strongly implies that Marianne is lying about Newt’s behavior and attitudes.
