NEW YORK  – Elizabeth Edwards writes in a new memoir that news of her husband’s affair made her vomit in a bathroom.

In the book scheduled to be published May 12, Edwards says her husband, John, admitted to the betrayal just days after declaring his run for president in 2006. She says she wanted him to drop out of the race to protect the family from media scrutiny, but stood by his side anyway.

The former North Carolina senator went public with the affair in August after the National Enquirer reported he was the father of videographer Rielle Hunter’s daughter.

Elizabeth Edwards never identifies Hunter by name. But she says that while her life may be tragic, Hunter’s is “pathetic.”

An advance copy of the book, “Resilience,” was obtained by the New York Daily News.
