Steven Crowley, 32, of Berkeley Street, appeared at Burton Magistrates’ Court on Friday charged with assaulting Terri Allen on August 9.
Andrew Bodger, prosecuting, told the court that Crowley had experienced difficulties with drink and drugs since September 2012.
He said that Crowley had been drinking on the day in question and the couple had argued. Crowley pushed Miss Allen to the ground, got on top of her, started to hit her, banged her head and bit her three times.
When interviewed by police Crowley said he could not remember anything because he had been drinking.
Two months before the attack her collar bone had been broken when he pushed her to the floor.
Mr Bodger said: “He acknowledges he has a bad temper and probably had assaulted her and bit her. He said he gets in such a rage he goes blank.”
Miss Allen’s injuries included a swollen eye, bruises and bite marks.
Mr Bodger read out a statement from Miss Allen, who was at the court, which said: “I admit nagging him and he would give me a backhander to shut me up. He never hit he when he was sober.
“He came upstairs and passed out on the landing. I shouted ‘Steve, get up’, he got up and got on the bed and then attacked me. After his blackout he said ‘oh no, what have I done?’”
The statement went on to say that “It has taken this to make us realise we can’t live without each other.”
She also requested that bail conditions - that prevented Crowley from seeing her - were dropped.
Crowley, who was without legal representation, told the court: “I deeply regret inflicting pain on someone I love.”
In sentencing, magistrates called the offence ‘serious’, adding that drink and drugs were no excuse.
Miss Allen was in tears as Crowley was led to the cells.
