Pridemore initially was charged with aggravated arson, a first-degree felony, after authorities said she attempted to burn down the family trailer.
"The complainant called and said there was a female there who appeared to be under the influence of something," Huron County Sheriff's Major Greg Englund said.
Deputies were called to the scene at 1:09 a.m.
"The female had set fire to the kitchen and the complainant was able to put the fire out by using a child's coat," Englund said.
Pridemore is the mother of two children who were sleeping in the trailer at the time of the incident. Another male subject also was sleeping in the trailer at the same time, Englund added.
"The woman did live there, but there was an argument after the male told her he was moving out with the two children," Englund said.
"The woman pulled out a disposable lighter and set some things on fire in the kitchen and made the statement, 'if she couldn't live there, no one was going to live there,'" Englund said.
"Sgt. Todd Wagner and Deputy Ted Evans located the female in the back bedroom and arrested her without incident," he said. "The Norwalk Law Director's office charged her with aggravated arson because there were people in the home."
