I did not watch that video but have seen other stuff on the topic.
She owns him, looks like classic Elder abuse to me.
He can't even speak without looking at her for permission to talk. And if you have time, go look at all her social media, she's just using him as a prop. If I were a member of Bill's family I'd be concerned.
She owns him, it is kind of sad to see.
If he roles were reversed, just imagine what would have happened already, but because she is a young women she's getting away with what I see as the early signs of elder abuse/brainwashing. This doesn't look like the classic women using a man for money, it looks much worse than that. I saw an interview with the two of them (they were on a beach), and he kept looking over to her as to ask permission to talk, it was like watching a battered wife talk to the cops, ya know looking over her shoulder making sure she was saying the right thing.
Again, if I were a member of Bill's family I'd try my best to get him away from her, she's scary, it ain't just about the money for her, something is off with her, she ain't right.
