Adanma Wokoh from London also said her faith is helping her recover after she fell victim to 43 year old Danish national Lasse Hartmann, to whom she had been engaged.
Speaking after Mr Hartmann was found guilty at Snaresbrook Crown Court of 22 counts of fraud, she said: "My faith, family and friends are helping me recover.
"As bitter as this was, I want to share my experiences with the world so other people can avoid the grief and pain I had to go through."
Ms Wokoh, a lifestyle blogger, has warned other people about the dangers of so-called "love fraud" as she claimed Mr Hartmann swindled her out of nearly £13,000.
Posing as a multi-millionaire wine trader under the alias of Lars Petraeus, he duped Ms Wokoh and her professional contacts into investing into wine packages which never arrived.
During their 18-month relationship, Mr Hartmann gave 32 year old Wokoh a £20 engagement ring he claimed was worth £50,000.
Described by police as a professional fraudster, Mr Hartman, from north London, embarked on the 17-month scam to fund a gambling habit.
She added: "People may think they will never be a victim of a con artist but I'm testimony it can happen to anyone.
"I went into the relationship hoping to find my life partner and finding out it was a sham almost broke me. When you hit rock bottom, the only way is up.
"While I'd never wish this on anyone, it's made me stronger in the process.
PC Alex Ramsay from the Metropolitan Police said of Hartmann: "He exploited everyone around him, not least the woman who thought that she was going to marry him.
"He used her status as a respected food blogger to give him credibility and from there managed to convince a number of businesses to go into partnership with him.
Hartmann, of Cardinals Way is due to be sentenced at Snaresbrook Crown Court on 28th April.
