George Kennedy Temple sliced GKT into Julie Rutherford’s stomach with a Stanley knife and told her: “You’ll always remember me,” at a home in Wester Hailes.
The victim also suffered cigarette burns to her arms, legs and torso during the horrendous abuse.
Temple today returned to the dock after admitting assaulting the 36-year-old to the danger of her life between April and October last year. Judge Lady Dorrian told the thug: “This case displays an appalling history of violence and abuse.
“It is hard to believe that a human being could behave towards another in such a depraved and monstrous way.”
She also ordered the 40 year-old to be supervised for a further six years on his release.
The attacks took place at a property in Westburn Grove after the couple began dating in June 2009.
