A woman stabbed her boyfriend to death with a kitchen knife after he told her of his plans to end the relationship, police said.
Ellishia Allen, 28, had been with 39-year-old Karl Bloxham for around five years when she stabbed him in their shared flat in Spruce Grove, Hucknall, Nottinghamshire.
Allen appeared at Nottingham Crown Court on Wednesday and pleaded guilty to murdering Mr Bloxham on July 29 last year, Nottinghamshire Police said.
She was told she will serve a minimum of 14 years behind bars.
Speaking after the sentencing, Detective Inspector Andy Bateman of Nottinghamshire Police said: "I feel enormously sorry for the parents of Karl Bloxham and for his sister and friends.
"I'm also conscious that he had children from a previous relationship and I'm very sorry they have been deprived of him.
"Today's events won't bring him back but I would hope that Allen is able to complete treatment in prison and have time to reflect upon her actions."
