The mother of a pregnant woman who was stabbed to death by her boyfriend says she will live with the pain and anguish of her loss until the day she dies.
Christopher John Anderson, 41, pleaded guilty in November to manslaughter over the death of his partner, Allira Green, inside a Maroubra unit in August 2013.
The 23-year-old was five months pregnant when she he fatally stabbed her in the chest, piercing her right lung and going into her heart.

Anderson was originally tried for murder, but that trial ended in a hung jury.
Speaking in the NSW Supreme Court on Friday, a teary Nadia Green-Simms mourned the loss of her daughter and the unborn grandson she will never meet.
'A life not even lived, taken in her prime. A grandson denied,' she told Anderson's sentencing hearing.
'He never got the chance to breathe or meet his family.'

ShareIn a tragic coincidence, Ms Green-Simms has spent her career helping victims of domestic violence.
But after domestic violence claimed her own daughter, she said she could not carry on with her work.
'All I can see is what she went through,' Ms Green-Simms said on Friday.
The court heard that two plain-clothes police officers had knocked on Ms Green-Simms' door at two in the morning to break the news of her daughter's death.

In the first trial which ended in June, Anderson said he was acting in self defence when Ms Green (pictured) was stabbed and was trying to save her unborn child from her 'ice' addiction
'I will never forget the looks on their faces, as I had seen it many times (in my work),' she said.
'The pain and anguish never stops.
'I will never get over it until my dying day.'
Anderson will be sentenced at a later date.

The relationship between Anderson (left) and Ms Green was described as 'volatile'
In the first trial which ended in June, Anderson said he was acting in self defence when Ms Green was stabbed and was trying to save her unborn child from her 'ice' addiction.
His defence said Ms Green was high on drugs and had launched herself at him with a knife.
The crown said the pair had a 'volatile relationship' and Anderson had struggled with two of her friends at the unit before she was stabbed.
It was also claimed during the trial earlier in 2015 that Anderson had changed his clothes after the stabbing.
