The man, 37-year-old Damon Mundy, told officers he and his girlfriend were going to a friend's house when his ex-wife showed up. Investigators determined the woman, 30-year-old Amy Napper, had been following him.
Mundy told police Napper slashed his tires and he tried to stop her.
Police said that's when she turned the knife on him. Mundy was stabbed several times in the chest.
He says Napper went around the building and came back -- saying to go ahead and call the police because she already hid the knife.
The man was taken to San Antonio Military Medical Center.
Napper was arrested on a charge of aggravated assault -- family violence.
