Jack Rayson, 26, previously pleaded guilty to criminal damage relating to him kicking a letterbox and punching a hole in a door, and pleaded guilty to sending malicious communications relating to text messages sent to the same woman on June 14 last year.
He was last week cleared by a jury of an offence of common assault against her on the same date.
Rayson, of Chiltern Gardens, Dawley, who has previous convictions, was on prison licence at the time and was recalled to custody following his arrest to complete that previous term.
He was jailed for a total of three months for the offences at Thursday's hearing at Shrewsbury Crown Court.
Sentencing him Judge Anthony Lowe said: "By your own admission you accept that it was a violent relationship. You're prone to losing your temper because you have problems that need professional help. You are advised to seek that help when you are back in the community."
A further common assault allegation relating to him raising his fist was dismissed after the court heard that the Crown Prosecution Service would not proceed with it.
Mr Paul Smith, defending barrister, said: "He will definitely be released in September, but there is a possibility he could be released as soon as he reaches half way to whatever sentence this court will give. It is about fairness. He has been in custody since last summer."
Rayson, who has autism spectrum disorder, must serve half the term before being considered for release. He must also pay the victims' surcharge. Applications for restraining orders were rejected.
