If she is so worried about you doing things to limit your income why doesn't she STOP and THINK (novel concept, I know) how her actions cause such massive amounts of stress on a household. I mean what? Will she only be satisfied when you and your children have absolute nervous breakdowns or your immune systems become compromised from stress?
I have been trapped in the family court system in this "fine" state for 24 months. I don't have children so I can't begin to imagine your situation. Stay strong!
