A man attacked his partner after discovering her asleep at a neighbour’s house, Lincoln Crown Court was told.
Shaun Bennett harangued his partner when he found her but later lost his temper.
Phil Howes, prosecuting, said that Bennett then began to hit the woman.
He said: “He punched her to the face at least 10 times before she lost consciousness.”
During the incident the woman suffered a fractured left cheekbone and a cut to her lower lip.
Bennett, 37, of Harpswell Close, Gainsborough, admitted inflicting grievous bodily harm as a result of the incident on March 24, 2015. He was given a two year community order and ordered to complete a building better relationships course. He was also given a rehabilitation activity requirement of up to 40 days.
The court was told that Bennett had already served the equivalent of a 12 month jail sentence while on remand awaiting his court appearance.
Sunil Khanna, defending, said the victim has since expressed a desire to resume her relationship with Bennett.
Judge Simon Hirst, passing sentence, told Bennett: “People who beat women causing these sort of injuries go to prison. However, in your case you have already served the equivalent of a 12 month sentence. It seems to me that because, and only because, you have served a 12 month sentence I can take an option that may not only help you but may help your victim.
“If you breach the order and are before the court again then custody is inevitable.”
