Billie Dunn said investigators found disturbing messages about her in Adkins' cell phone Thursday. She didn't wish to go into detail, but described the content as "threatening."
Dunn said Adkins can't come on her property for a year under the order she filed Friday.
"He made threats against me. I don't think he sent them anywhere. They were just on the memo pad...I got scared and I didn't want him to be able to come over here at all anymore," she said.
Dunn was arrested Thursday after police came to her house looking for Adkins, and she lied and said he wasn't there.
Officials took Dunn into custody and questioned her. She was released Friday on a $6,500 bond.
"They're suspicious Shawn keeps trying so desperately to get back with me because they think I know something, I'm hiding something for him," she said.
Dunn said she has no plans to see or speak to Adkins again.
"Even if by some miracle Hailey walked through the door and he had nothing to do with that, there's too many problems between us now," she said.
Dunn said Adkins hasn't tried to contact her since she filed the order.
