A 40-year-old grandfather who bloodied his teenage girlfriend and threatened to rape her friend will be eligible for parole in April next year.
The man, who cannot be named for legal reasons, fronted the ACT Magistrates Court on Monday, having previously pleaded guilty to two counts of common assault and two counts of assault occasioning actual bodily harm.
Magistrate Beth Campbell said the charges stemmed from two "disturbing", "demeaning" and "humiliating" incidents, both of which proved the man didn't know how to have "a mature, grown-up relationship with women".
The first incident, which happened on December 23, 2019, involved the man grabbing a woman in her 20s - who he lived with at the time - and slamming her head into a door frame.
Prosecutor Katrina Marson said the man called the woman a dog and threatened to rape her before police arrived and she told them she was "petrified".
The second incident, which happened on April 18 this year, started when the man struck his 17-year-old girlfriend with his elbow and pushed her to the ground.
She hit her head on a bed frame on the way down, before the man straddled her and punched her in the head. He later dragged her from the Isabella Plains house by her hair.
Ms Marson said the man told the 17-year-old to wash her hair before police came in his "cynical", "manipulative" and "sinister" attempts to mislead them.
Ms Campbell said while the man and his girlfriend's age difference made those in court "catch our breath", the victim was deserving of care and guidance, particularly at such a young age.
The magistrate said the man's four children and two grandchildren would look to him as a model of how they should act, and his "irrational, violent, agitated [and] aggressive" behaviour had let them down.
"It's appalling conduct, it's shameful conduct," Ms Campbell said.
"You're treating these women, or this one in particular, like a possession."
The man's lawyer Tich Pasi said his client took full responsibility for his actions, and that included him being prepared to serve a further term of full-time imprisonment.
Ms Campbell noted the man had already served more than six months in jail on remand for the December and April offences, and sentenced him to a total 19 months in prison.
She said the man would have a 12-month non-parole period, meaning he would be eligible for release in April 2021.
