Clearly this man simply isn't leading his soon-to-be ex-wife sufficiently well, otherwise I have no doubt she would be a fine, upstanding, submissive woman who would always put her marriage first.
Some things can't be fixed. Some people can't be fixed. They're just broken, or in some cases, simply unfit for specific purposes. Just as not every man is capable of being an NFL quarterback, not every woman is capable of being a wife and mother under the current legal regime. This woman might be capable of being married in Saudi Arabia or another country where such behavior would not be legally tolerated. But not in the USA, where it is not only tolerated by the law, but protected.
