A terrified woman was forced to barricade herself in a room at her own home after being viciously attacked by her boyfriend who was high on cocaine, a court heard.
Lee Russon punched his partner in the face and repeatedly stamped on her, Wolverhampton Crown Court was told.
Mr Mark Rees, prosecuting, said it was a vicious and violent assault. Russon was locked up for a year.
He said: "There was blood on the carpet. She was begging him to stop and curled up into a ball to protect herself but he continued to stamp on her before walking off as if nothing had happened.
"This gave her the chance to move the settee across the door to the room and phone the police."
Russon, aged 30, was arrested at the Willenhall address of the victim - with whom he had been living for five years - when officers arrived soon after being alerted at 3.50am on July 26.
Mr Rees told the court: "The defendant had taken cocaine and his partner knew there was likely to be problems because of the mood swings this created in him.
"He pulled her off the sofa, called her names, punched her in the face and started to stamp on her body."
Russon had broken a wrist of the woman by violently pushing her to the floor after returning to their home drunk in an incident two months earlier which was not been reported at the time because he took her to hospital for treatment, it was said.
Mr Michael Trevelyan, defending, told the court: "These events were not premeditated. They were the result of his drug and alcohol abuse."
Russon, previously of Cumberland Road, admitted assault and causing grievous bodily harm and was jailed for 12 months by Recorder Geoffrey Kelly.
Recorder Kelly told him: "These were shameful and cowardly attacks on someone whom you, at some stage, loved and presumably loved you.
"One of them involved a sustained assault on a defenceless young woman in her own home when she was doing nothing at all to aggravate the situation."
