Elizabeth Edwards says it was not easy to leave former senator and presidential contender John Edwards in the wake of his affair.
Edwards says in a new chapter of her memoir released Tuesday that she tried for two years to "reinvent" her role as wife before deciding at the end of 2009 that she did not want to try anymore.
The Edwards' have since separated and he has acknowledged fathering a child with his mistress during his 2008 campaign for the White House.
Elizabeth Edwards says in her book "Resilience" that it was not easy to leave the marriage because she saw 30 years of memories in him. She is battling cancer and says she hopes to live long enough to see her youngest child graduate high school.
