Deputies said the woman, 31, gave her friends the boot, told her fiance to leave, too, and then started hitting him in the face.
When he left the house, they say, she tackled him football-style, punched him some more, threw his watch into the bushes and broke his glasses.
Responding to a 911 call from her son, deputies arrested the woman for investigation of fourth-degree assault.
Sheriff's Lt. Kathy Collings said the woman was released from jail later Thursday.
There's no word on whether the marriage took place.
