Zues, first, welcome to the neighborhood. I'll bring over a pan of brownies later. I'll leave them on the porch and ring the door bell and run, lest we actually meet and become friends.
I'm sorry what you are going through with the unreasonable financial demands. I'm always surprised to hear that someone's D is playing out that way, having been through a D myself. There was never any possibility of my taking 60% of his income and demanding more, I don't understand how that'viable for anyone. I agree with Cadet and Job, a judge very well may be your best bet here.
As far as your being on the right board, not all of us here on Surviving are trying to save our M. I'm not. This board is more about trying to negotiate our lives and our Xs and sometimes new relationships. It's always full of support and wisdom, and I'm glad you are here.
