Bill Daitchman got some bad news this week: His insurer is breaking up with him.  Daitchman and his wife, who own a graphic design business in Santa Cruz County, Calif., each pay $350 a month for a health insurance plan from Anthem Blue Cross on the Covered California exchange. But Anthem announced Tuesday it’s pulling out of most of the state’s individual markets, citing the uncertainty swirling around the Affordable Care Act.
