Keith Stuart Cornish was convicted of stalking after his ex-partner told magistrates he made her feel like a prisoner.
Cornish, 50, of Field Way, Stanton, had pleaded not guilty to stalking Amanda Rose.
Miss Rose said she had begun a relationship with Cornish in late 2004 or early 2005. They had got back together after he was convicted of assaulting her in 2007 and were back together within a year of him being given a warning for harassment in 2009.
But she said the relationship completely broke down in 2012, though she allowed him to stay in her Ingham home until 2013.
Miss Rose, an activities co-ordinator at Cornwallis Court old people’s home, told the court of visits he made to the home after the break-up and of seeing him walking past on several occasions.
In September 2013 a colleague told her Cornish had applied to be a volunteer minibus driver at the home.
“He could go to any home in Bury to help but I couldn’t think why he would want to come to where I work,” she said.
She said that while he lived in Ingham he had ‘little contact with her neighbours’ but after moving out she had seen him picking them up in his car. He had also started using a massuese who lived almost opposite her.
After he had ben charged with stalking in early December, he had been bailed with conditions not to contact her. But she said she while in town with residents and other staff when Cornish approached and spoke to colleagues and had then gone into the Corn Exchange after seeing her enter.
Carol Huston, prosecuting, asked how Cornish had made her feel.
She replied: “I’ve been asked to start work at different times and go home at different times. We’ve had to put extra security in at the home. It’s a bit like being a prisoner.”
Cornish told the court he had known the home’s other activities coordinator since school and had volunteered because he knew the home and staff. He said Cornwallis Court was between his mother’s home and his place of work.
He said he had spoken to the neighbours when he lived with Miss Rose only when she was not there because of a dispute she had had with them and after he moved out had met them in town.
He said when he saw Miss Rose and six staff and residents from the home in Bury he had ignored here and only spoke to the others he knew. The only reason he had gone into the Corn Exchange was because his baby granddaughter needed changing and feeding.
David Stewart, defending, asked: “Did you think your conduct was harassing her?”
Cornish said: “No , sir, not at all.”
Cross examined by Mrs Hutson about the 2009 harassment warning he said: “I admit I lost the plot. There was a strange car on her driveway and it was there for a period of time.”
Announcing a guilty verdict, chairman of bench Graham Higgins said: “We found Miss Roase a credible witness. We’re satisfied through this series of events you should have known your conduct amounted to harassment”
Cornish was remanded on bail for reports until June 30 with conditions not to contact Miss Rose, not to be within 5m of her and not to enter Ingham unless on the A134.
