A man who launched a six-week terror campaign against his ex-partner has been jailed.
Bernard Elvis Boswell, 31, bombarded the woman with threatening and upsetting phone calls and text messages throughout June and July.
In one message he threatened to stab her family dog and another contained a photograph of himself threatening to commit suicide, Preston Crown Court heard.
On July 8, Boswell, of St Alban’s Road, Blackpool, tried to get into the woman’s house and an argument broke out between the pair.
The police were called and Boswell was arrested.
He told officers the messages he had sent were “awful” and later pleaded guilty to putting a person in fear of violence.
The couple separated three years ago and the court heard there was no background of violence or loss of temper between them.
Boswell – who works as a labourer – has a previous conviction for robbery.
Judge Mark Brown, sentencing, said the harassment was so serious he must impose an immediate prison sentence.
He said: “For a period of around six weeks you were involved in a campaign of harassment towards her.
“You literally bombarded her with telephone calls and texts, some of which were very unpleasant in tone.
“I am quite satisfied that you were motivated out of a sense of spite and vindictiveness towards her.
“You were clearly intending to make her life as miserable as possible and I have no doubt your offences had a significant impact on her life.”
He jailed Boswell for six months and made a five-year restraining order.
Boswell must also pay a £900 criminal court charge.
