Andrew Polson, 53, of Bearsden, Dunbartonshire, was found guilty by a jury of stealing £186,000 from the 72-year-old woman between May 2021 and March 2022.
He induced her to transfer money to him under the false pretence that she was investing in two homes and a lettings firm.
However, prosecutors from the Crown Office and Procurator Fiscal Service (COPFS) proved that Polson put his sole name on the title deeds of both properties without telling her and used the woman’s money to fund his own lifestyle.
He was sentenced at Glasgow Sheriff Court after being convicted of being involved in a fraudulent scheme.
He was also found guilty of embezzling £9,018 from Cumbernauld-based radio station, Revival FM.
He had previously been the company’s financial director and latterly held the position of Chief Operating Officer.
A non-harassment order was also granted for a period of three years and he was disqualified from being the director of a company for five years.
Fraser Gibson, Procurator Fiscal for Glasgow and Strathkelvin, said:
“Andrew Polson exploited the kindness of his former partner to fund his own lifestyle.
“Romance fraud is a particularly appalling crime that has both an emotional and financial impact.
"Financial crime cases can be complex, but the evidence presented during the trial made the criminal activity clear.
“COPFS will continue to do all that we can to hold offenders to account while supporting those affected through the prosecution process.”
Polson met the woman at church and they worked together at Revival Radio Ltd.
They were intermittently in a relationship from 2013 and resumed their relationship during the pandemic.
Evidence heard in court revealed that in May 2021 Polson persuaded her to pay £40,500 to buy out his ex-wife’s share of a house in Bellshill, Lanarkshire.
The woman believed they would jointly own half of the property and that she would receive half of any rental income.
But prosecutors showed Polson became the sole owner a month later.
On 14 January 2022, the complainer transferred £146,000 to purchase a home in Bearsden, Dunbartonshire, which she understood would be solely in her name.
However, six days later Polson registered himself as the sole owner.
The woman was also depositing around £200 a month into AA Lettings, a firm they jointly established to cover repair costs on the two properties.
The court further heard that Polson used Revival Radio’s direct debit card to pay for a casino outing and property refurbishments.
Around March 2022, the woman saw a bank statement for AA Lettings and suspected she was the victim of fraudulent activity.
After examining the accounts, she believed she was funding Polson's lifestyle, which included paying for weekends away and his mother-in-law's 70th birthday party.
Following discussions with bank officials, police were alerted and an investigation began into Polson’s conduct.
Polson will now be subject to confiscation proceedings under Proceeds of Crime legislation to recover monies illegally obtained.
