A day after the plea, she told ABC's "Good Morning America" she wasn't sure she wanted to stay married. ABC first reported the divorce Thursday.
She said the couple lived "like gypsies" after George Zimmerman was released on bail, spending nights in a 20-foot trailer in the woods.
Her husband wasn't in court with her last week as she was sentenced to a year's probation and 100 hours of community service.
George Zimmerman was acquitted of second-degree murder in July.
