Scott Callaghan, 44, brutally assaulted his ex-partner amid a 15-year horror campaign of domestic abuse.
Callaghan’s vile acts included throwing a pram at her after she got home late from a Take That concert.
He also refused to let her sleep with bedding on and kept her awake one night by poking her with his finger.
Callaghan kept tabs on his former partner even after she fled to Newcastle to get away from him.
He sent her a map of Newcastle along with a string of violent threats including to behead her new boyfriend.
Callaghan was found guilty at Glasgow Sheriff Court of assaulting the woman to her severe injury, permanent disfigurement and danger of life.
He was further convicted of behaving in a threatening or abusive manner and engaging in a course of behaviour which was abusive of his partner or ex-partner.
Sheriff Tony Kelly imposed a 99-year non-harassment order on Callaghan which prohibits any contact with the woman, as well as the jail sentence.
The charges spanned between January 2004 and March 2019 at properties in Glasgow’s Drumchapel and Summerston.
The court heard that Callaghan was “aggressive” to his then partner throughout the relationship and “belittled” her.
Callaghan pushed her to the ground while she was pregnant, which was seen by a young girl at the time.
Prosecutor Danielle McGuinness put to Callaghan in his evidence: “You hit her head with your head so hard that you gave her two black eyes when she was pregnant.”
Callaghan replied: “No and I never seen her with two black eyes.”
The trial was also told that Callaghan pinned the woman up against a wall and put his hands around her neck.
She went to a Take That concert and was confronted by Callaghan when she returned home for taking “too long to get home.”
Miss McGuinnes said: “You got so angry, you took a pram from the hall and threw it at her when she was lying in bed.”
The fiscal depute also stated that Callaghan “took bedding from her” as she “didn’t deserve covers.”

She added: “What about nudging and poking her for hours so she didn’t sleep?”
Callaghan: “That didn’t happen, I have never lifted my hand to any woman.”
The hearing was told that the woman suffered a broken arm in a separate incident in Glasgow city centre in which Callaghan claimed she “stumbled” over a central reservation.
Miss McGuinness refuted this stating: “You turned up to her night out and she felt the need to leave as you were jealous and drunk.
“In that argument, you ran at her and pushed her.”
The hearing was told that Callaghan had to borrow money for milk after he spent his money by gambling.
The fiscal depute stated that Callaghan was kicked out of a hotel in Tenerife after he “smashed the room up.”
Miss McGuinness added: “At the airport, you were not allowed on the flight.”
Callaghan replied: “The captain didn’t let me on.”
On another holiday to Craig Tara holiday park, security was called to get Callaghan due to his “threatening and abusive behaviour.”
Callaghan later told the trial that he refuted Miss McGuinness’ suggestion that in another incident he let the door open for the woman’s cat’s kittens to “run away.”
After the pair split up, she moved to Newcastle and received a number of threatening texts and voicemails from Callaghan.
This included a map and later on messages stating: “B****, I am coming to Newcastle, I’m going to get the jail.
“We are coming right through the now to f****ing kill yous and f***ing show you up.
“I will f***ing cut his head off, you f***ing idiot.”
Callaghan stated to jurors that the woman was a “good actor” and was “like her sisters who we call the Black Widows of Drumchapel.”
