She confirmed that I would have to give him 30% of my pre-tax earnings, yikes,
Remember, though, that alimony is tax deductible to you. So your actual cost, after tax breaks, depending on your tax bracket, might only be 70-80% of that amount. (My H's tax bracket is so high, that between state and fed taxes, what he pays me in alimony only costs him about half as much).
