It could very well have been her husbands fault.
The guy sounds like a entrepreneur and they sound like they are well to do.
He could've finessed his wife for years. Ive heard of a lot of men who will say they want children....but
Year one: "Babe we just got married lets enjoy our time alone!"
Year three:"babe the business is just barely getting by, i don't think we can have kids...."
Year seven: "babe the business and your career are doing so well right now! we're just too busy!"
Year 10:"we just bought the condo in malibu, we can't maintain our lifestyle if we add kids in the mix!"
Year 12:"I think we're too old for kids now and I aint adopting no nikkas"
And so on.
But if she knew from jump he didn't want kids then the blame falls squarely on her shoulders.
