A man used lighter fuel in a bid to start a fire following an argument with his partner, Lincoln Crown Court was told.
Matthew White sprayed the fuel around the woman’s home and threatened to set fire to curtains.
Jonathon Dee, prosecuting, said that White then tried to set light to the curtains leaving his partner ‘incredibly scared’.
White only succeeded in causing a small scorch mark but then attacked his partner as she tried to get away.
Mr Dee said: “During the course of the incident he punched her several times. She forgave him and the relationship continued.”
The couple continued to have arguments, often about White’s gambling habit, and the following month an incident took place in which he was so aggressive that his partner was so scared she locked herself in her bathroom.
Soon afterwards she left the room only for White to then grab hold of a knife and confront her.
Mr Dee said: “They struggled and she was able to get away from him.”
A further incident took place the following month before his partner told him the relationship was over and White admitted himself to Grimsby Hospital.
White, 26, of Hamilton Street, Grimsby, admitted arson and common assault in February this year. He also admitted common assault in March and criminal damage as a result of the April 5 incident. He was jailed for 12 months.
Judge Sean Morris also imposed a two year restraining order which bans White from contacting the woman who is now his ex and from going within 50 yards of her home in Market Place, Tetney.
John McNally, defending, said White’s gambling addiction was the source of arguments and he also suffers from mental health problems.
“He can only express his remorse.”
