Input: Nashville Mayor Megan Barry  has admitted that  she  had an extramarital affair with the former head of  her  security detail.
"I'm embarrassed  and I am sad  and I am so sorry for all the pain that I have caused my family and his family "  she  said at a news conference Wednesday. "I know that God will forgive me  but that Nashville doesn't have to. ... I hope that I can earn your trust back and that you will forgive me."
Barry has stated that  she  will not take leave or resign over the affair  as Nashville Public Radio reported. "I made a serious mistake  but this is not a tragedy "  she  said.
This comes at a politically sensitive moment for the mayor  as  she  tries to persuade the city's voters to endorse a $5.4 billion transit infrastructure plan. That measure will be voted on in a May referendum.
 Barry  has also recently faced personal tragedy —  her  only son died in July of a drug overdose.
 She  has denied improper use of taxpayer money during the affair with  her  security head  identified by the Tennessean as Metro police Sgt. Robert Forrest Jr.
