I think cleaning up your financial house was the most important thing you could have done, and it'll still take a while for her to get over it.
Nothing stresses out a woman, especially one with kids, as much as financial problems. No matter how much she "knows" better, deep in her mind, that's your job and if it turns out you can't do it, she's made a terrible mistake in settling down with you.
Did she work before all this trouble started? If not, she may on some level still be holding the fact that she now has to work against you.
a fine and enviable madness, this delusion that all questions have answers, and nothing is beyond the reach of a strong left arm.
