Elizabeth Edwards is on the cover of the latest People Magazine and offers a candid interview inside of the anguish, pain, and decisions that she faced after learning of her husband's affair with a former campaign aide, Rielle Hunter. Recognizing that she has been diagnosed with a terminal illness that could leave her three children without a mother was reportedly a factor in her decision to stay in the marriage.
Children are one of the reasons that women stay in a marriage where a husband has strayed, but it shouldn't be the only reason. Women's income generally drops an average of 16% while a man's increases by 23% according to the NY Times. They often don't have the earning power of their spouses or may have been out of the workforce due to the demands of child raising.
