A man forced his way into a flat he shared with a girlfriend and attacked her.
David Whyte repeatedly slapped his partner round the head and then spat in her face.
Whyte, 31, of Hornby Road, Blackpool, pleaded guilty to assault and causing damage.
He was bailed for pre-sentence reports and will be sentenced at a later date by Blackpool magistrates.
Martine Connah, prosecuting, said Whyte barged open the front door of the flat he lived at with his partner on September 20.
He pushed her to the floor, slapped and spat at her.
The girlfriend had now said their relationship was over.
Steven Townley, defending, told magistrates his client had said he had been subjected to some provocation from his girlfriend.
