North Carolina ? Elizabeth Edwards said she became physically ill when her husband, Democratic presidential candidate John Edwards, told her he was having an affair.

“I cried and screamed. I went to the bathroom and threw up,” Edwards says in her new memoir.

Elizabeth Edwards, 59, who lives outside Chapel Hill, N.C., writes that John Edwards told her of his affair with campaign videographer Rielle Hunter shortly after he announced his second run for the presidency in December 2006 in New Orleans.

Elizabeth Edwards writes that she wanted her husband to quit the presidential race to protect the family. She writes that later events proved her right.

The memoir, called “Resilience,” is scheduled to be published May 12 by Broadway Books. The New York Daily News first reported the memoir’s contents Thursday.
