Thomas Gannon, 35, told Brooksville authorities that the couple's troubles began when his 31-year-old girlfriend, Tina Cash, "unfriended" him on Facebook, the St. Petersburg Times reports.
According to the Hernando County Sheriff's Office, Gannon claims Cash not only nixed their online friendship -- she also changed her relationship status on her Facebook page.
Gannon reportedly stated that when he asked Cash about the Internet break-up, she started throwing things at him, hitting him in the face with a framed flag that once belonged to his great-grandfather.
Cash told officials that she wasn't the only person throwing things, stating that Gannon also hurled objects at her and punched her in the head, UPI reports.
Both have been charged with misdemeanor domestic battery.
