Heaven only knows what really went on, but it's entirely possible that he did put a great deal of pressure on her, even if she was unable to convince a second jury that it met the legal requirement for marital coercion. Being a successful professional person doesn't make you immune from abuse or violence, even, let alone undue pressure and bullying at home.
I can quote several examples of colleagues who are or have been dynamic, professional, experienced, qualified skillful women - you would never have dreamed what was going on behind closed doors. Senior managers in respected fields - and yet they were being abused by their partners/husbands. How many more women are putting up with pressure and bullying that falls short of the definition of domestic abuse?
It was very wrong of her to try to pin the blame on an innocent third party, though.
