So you are saying that he should have told his wife that he was giving charitable money to any woman, any man, any charity, or just this woman in particular? My wife expects me to handle certain aspects of our lives and does not want to hear about the day to day decisions I make, even regarding money. That's my job. She would probably get suspicious if I did start informing her of everything. She would figure I must be covering my tracks or something.
Just a question. Are you married?
At my house we discuss anything we regard as "big ticket" before we just buy something, but I know many people where the wife leaves that to the husband and a couple of instances where the wife makes those decisions.
We don't know how the Cains chose to do it, but we do know that Mrs. Cain was a homemaker and that Mr. Cain had a very large income. What is the lower level of "big ticket" at my house probably wouldn't even register at the Cain's.
We also don't know the amount of money he gave her (both parties refusing to disclose). If it was a hundred or couple hundred to help her avoid eviction or buy groceries and happened a couple times, no big deal to me. If he gave her 10s of thousands on a regular basis, that's another story--for me at least.
But whatever he gave her, she is a known liar and defamer proven in court and her own apology for having done so and getting caught at it. Her own accusations don't make sense and I don't believe her. Period.
