A woman whose lip was “completely severed off” her face by an ex-boyfriend detailed in an online post the emotional and physical trauma she faced during the ordeal, and how she thought she was going to die.

Kayla Hayes, 19, recounted on Facebook Thursday the day her ex-boyfriend, 23-year-old Seth Fleury — who was her “worst nightmare” — bit her bottom lip off during an uninvited kiss as she tried to break up with him in October 2017.
