You need to see A GOTTMAN CERTIFIED THERAPIST and both get couseling,She is feelling powerless and not gertring her emotional life needs met by you, home, family, and self. She needs to feel autonomous and secure. The way you handle money is a sore spot and a way to keep score. This is her way to get your attention. If she wanted to leave you would be on your butt with a restraining order to get you out then serve you papers. The way you handle it will be a testament to come through as a loving partner marriage or you get taken to the cleaners via family court.
