Controlling Paul Oxberry head-butted his partner when she was pregnant with his child.
The 19-year-old had been in a relationship with Sandra Forbister for nine months when he attacked her after a drinking session.
The pair had been out together, on May 31, when an argument broke out as they made their way home on a bus. Which ended with Oxberry head-butting her.
Rebecca Laverick, prosecuting said: “She said he was very controlling. He was always ringing her up and he didn’t let her go out by herself. She said he often becomes aggressive when he’s drunk but thought he wouldn’t do anything because the two children were with them. But he continued to be aggressive. She told him she wanted him to leave her alone. Then with out warning he head-butted her.”
Ms Forbister asked one of her children to call the police, but when they failed to get the phone working she managed to run to a nearby garden and dial 999.
Mrs Laverick added: “She said she’s not going to stay with Paul. She feels isolated from friends and family because he’s so controlling.”
However, the court heard the couple had since rekindled their relationship.
Oxberry, of Castle Street, in Hazlerigg, Newcastle, admitted assault by beating.
Kevin Kivlehan, defending, said: “He’s only 19 and has severe learning difficulties. He says he accepts the head-but. The two of them had been in drink and arguing all day and he had simply had enough.
Oxberry will be sentenced next month.
