Swansea Crown Court heard that the victim had been on a night out with work colleagues.
51-year-old Raymond-Jones, now residing at Gwynfor Road in Swansea, picked her partner up, but when they got home in Hendy, she accused him of being with another woman and demanded proof he was actually with colleagues.
Despite her partner showing her pictures his colleagues had taken, Raymond-Jones started kicking him, before lighting a cigarette and threatening “I’m going to f***ing burn you”.
She attempted to stub the cigarette out on his head, but he managed to push her away.
Raymond-Jones attempted to provoke her partner, claiming to have slept with other men in their bed, before she swung the wine glass she was holding at his neck.
The glass connected with the victim’s jaw and smashed, and blood began “pouring profusely” from the wound, Ms Donohue said.
The victim took himself to the bathroom and used a towel to stem the bleeding before tending to the wound. The following morning he visited his GP, but they were unable to treat him as the wound was too deep.
He attended hospital, and needed stitches for the four centimetre laceration to his jaw.
The incident was reported to police on December 22, and Raymond-Jones was arrested on January 12.
In interview, she said she was acting in self-defence and claimed her partner had kicked, punched and racially abused her. She said she had the wine glass in her hand and it made contact with her as she pushed him off of her.
However she later pleaded guilty to inflicting grievous bodily harm without intent.
The court heard 51-year-old Raymond-Jones had one previous conviction for two offences of battery in 2016, after she punched a woman and pulled her hair on a night out, and then smashed a wine glass in the face of a member of door staff at the venue.
“She’s ashamed of herself and she is remorseful about what’s happened and what she did,” said Emily Bennett, in mitigation.
“She takes responsibility for her actions.”
Ms Bennett said the defendant’s childhood in Neath “was nothing short of difficult”, and that she had been receiving support from the community mental health team.
Judge Catherine Richards said the offence was “seriously aggravated” by it being committed against the defendant’s then-partner and due to her “relevant previous conviction”.
She added that Raymond-Jones had “complex mental health difficulties”.
Raymond-Jones was sentenced 15 months, suspended for 18 months, and must complete 15 rehabilitation activity requirement days.
The victim was granted a one-year restraining order.
