David Petraeus' wife, Holly, threatened to divorce her husband in light of his extramarital affair with his biographer, Paula Broadwell, according to a source.

The scandal forced Petraeus to resign as CIA director and now it might cost him his 38-year marriage with Holly, with whom he shares two adult children. Their son served in Afghanistan and only last month the couple celebrated the marriage of their daughter in Berryville, Va., according to The Washington Post.  

David told friends the affair with Broadwell began in August of 2011 after he left the army.

"Holly is furious," a source close to the fami­ly told the National Enquirer. "David humiliated her in front of the whole world. Leave him? If it were me, I'd kill him! Holly told David, 'I want you out of my life!' - and threatened him with divorce."

"David has been falling all over himself, apologizing and begging Holly to forgive him," said the friend. "But she isn't listening. After all his lies, she doesn't believe anything he says anymore, and she's thinking about consulting a divorce attorney. Her marriage has already come crashing down. Now she's ready to pull the plug."

Holly is the assistant director for the Obama administration's Consumer Financial Protection Bureau, monitoring and investigating complaints from U.S. service members. She met David in 1973 when he was a cadet at the U.S. Military Academy at West Point and her father was the superintendent. They married a year later.

David once thanked his wife in a speech, saying she'd been " 'Mrs. Dad' for the bulk of the last decade while I've been deployed." Holly herself admitted that as a military spouse, she moved with her husband 24 times in 37 years of marriage, according to the news report.

Broadwell's book "All In: The Education of General David Petraeus," which included details from dozens of interviews between Holly and David, described how the couple met and fell in love. Broadwell also called their relationship "virtually unbreakable," according to the Daily Mail.
