July 24, 2008 — -- The husband of murdered North Carolina jogger Nancy Cooper is finally speaking out about the state of his marriage, admitting he cheated and claiming that his wife did, too.

"Three years ago, I made a mistake while married to Nancy," Brad Cooper said in an affidavit filed Wednesday in Cary, N.C., and obtained by ABCNews.com.

"I had a single indiscretion and slept with another woman one time," said Cooper. "I deeply regretted [and still regret] that it happened."

While Cooper does not disclose the name of the woman in question, an affidavit filed by his wife's friends identifies her as Heather Heider-Metour, but does not delve deeper into how Cooper met her or the details of their relationship.

ABCNews.com was unable to contact Heider-Metour for comment.

Family and friends of Cooper's wife have been pointing fingers at her husband since the jogger disappeared just after 7 a.m. on July 12 and was found murdered two days later. They claim Cooper was abusive to his wife and even threatened suicide at one point -- claims Cooper adamantly denies in his affidavit.

Police have not named Cooper, 34, as a suspect or a person of interest in his wife's homicide.

In his affidavit, Cooper also alleges that his wife admitted to having an extramartial affair around the same time that he says he revealed his own indiscretions.

"Nancy admitted that she also had an extramarital relationship while married to me, four years ago," Cooper said in the document. "Nancy insisted that she did nothing wrong, that her relationship with the other man only happened once, it wasn't sexual and that no one even knew his name."

The Coopers were attending marriage counseling, according to the affidavit, but in April 2008 Cooper's wife prepared a separation agreement. At the time of her murder, Cooper had not yet signed the agreement.

In addition to addressing the state of his failing marriage, Cooper wrote extensively about his ability to care for his two daughters, Bella, 4, and Katie, 2, who have since been in the care of his wife's family after they were awarded emergency custody last week.
