"Not before she got married, she didn't. Did she have those 'many lovers' prior to giving birth to Prince William? DOUBT IT!"
Correct. But technically it is ok to have a lover before you are married, if you aren't a true Christian. As to lovers before Prince William's birth (assuming after marriage), I agree she probably didn't have any. But if she had, the consequences would have been greater because Charles can't give birth to a bastard Prince. Had Diana cheated, she could have.
"Meanwhile her husband continued his adultery with Camilla."
That is not in dispute.
"Kind of reminds me of that Michael Schiavo that's been shacked up with some other women and been trying to kill his wife off for years."
I dispute that Charles tried to knock off Diana. In Michael's case, it's only human to want to move on if your spouse is incapacitated. It's human nature, not that it is right. Trying to kill her off, that's attempted murder. He should be investigated.
IIRC it is NOT ok. I think they do tests to make sure she is a virgin and not pregnant. So obviously it isn't ok if she had lovers prior to marriage.
As for Shiavo/Charles they both were HINO (husband in name only) THAT was the connection. However, remember there are different types of spouse abuse. It's just that in Charles' case the scars he left Diana with weren't visible. But, that doesn't mean they weren't devastating. to her well being.
In fact, sometimes the emotional and psychological scars are worse as they can take longer to heal than a black eye.
