A woman repeatedly bashed by a police officer has lived in "constant emotional turmoil" since the abuse, a court has been told.
Jonathan Charles Bettles physically abused the victim a total of 10 times at her southwest Sydney home, the cafe where she worked and in his car.
While serving as a senior constable for the NSW Police, Bettles punched the woman in the head and jaw, stomped on her left foot, and slammed her into her bedroom wall by forcing open a door she was trying to hold shut.
She felt too scared to call triple zero after being told "all police would be like him", an agreed statement of facts tendered in court revealed.
The 37-year-old used his position in the force to prevent her from filing an official complaint, the statement says.
"I know how the system works," he would tell her.
The woman has been left terrified after the abuse, she wrote in a written statement read to the court by her daughter on Wednesday.
"Since these events, I have lived my life in constant emotional turmoil, I no longer feel safe," she told the Burwood Local Court.
"I am not the same woman I once was."
The trauma from these incidents has left her with anti-depressant addiction, the statement revealed.
"I am afraid that eventually the pain will become too much to carry on my own," her daughter read to the court.
"The memories are too vivid, too haunting, too cruel, to face unmedicated."
Bettles abused the woman multiple times from the beginning of 2020 to mid-2021, his lawyer Bryan Wrench said on Wednesday.
The woman suffered in silence during the 18-month period, she wrote in her statement.
"I feared no one would believe me because of who he was," her daughter told the court
Mr Wrench did not deny the severity of his client's crimes.
"It is tough because it is really serious offending, we don't shy away from that," he told the court.
But he argued that Bettles' mental health was also serious.
"They are no doubt related to what's occurred," he said.
"They are deplorable and horrible incidents but I know they are related to the emotional outbursts caused by PTSD."
But prosecutors argued on Wednesday there was limited evidence of the link between Bettles' PTSD and the abuse.
Bettles has pleaded guilty to 13 offences, including common assault, assault occasioning actual bodily harm, destroying or damaging property, and perverting the course of justice.
Magistrate Christopher Halburd will sentence Bettles on Monday.
