A South Korean woman has been left with a broken heart and $50,000 of credit-card debt after she found out she married a man who already had a wife and two kids living in New York.

Rachel Lee, 43, of Uijeongbu, near Seoul, had her marriage nullified after finding out the truth about her 'husband', 40-year-old Army Master Sgt Scott Fuller.

Lee and Fuller started dating in August 2013 and were married just four months later - it was Lee's second marriage, but she believed it to be the first time Fuller was tying the knot.

She realized Fuller had a family when her new husband asked her to re-format his cellphone so he could sell it. While doing so, she discovered 'happy anniversary' emails that he had just sent to his other wife, Marianne.

Lee, a teacher, called authorities and filed a forgery complaint. Fuller was convicted in a Korean trial court and was sentenced to eight months in prison on October 31, 2014, Lee's lawyer, Howard Myerowitz, told the New York Post.

But soon after, Army officials reassigned Fuller to Fort Drum in upstate Jefferson County and have declined to prosecute him for bigamy or fraud, despite Fuller keeping up his ruse through a trial of allegedly false paperwork, Lee's lawyer claims.

False paperwork included a premarital certification on US Embassy letterhead that Fuller showed to South Korean officials in an attempt to show he was single, Myerowitz said.

Fuller also submitted a New York state judgement of divorce claiming that he and Marianne had divorced.

While Lee is still living in South Korea, Fuller is back at his New City, New York, home with Marianne, and their kids, a six-year-old daughter and four-year-old son.

Myerowitz, a Fort Lee, New Jersey, attorney who specializes in Korean issues, said that his client was devastated, and that she had been 'head over heels' for Fuller.

'It has been very, very tough for me,' Lee told The Post through a translator during a phone call from South Korea. 'Quite honestly, I do feel suicidal.'

Myerowitz is seeking restitution of the $50,000 in credit-card debt that Lee claims Fuller owes her.

'It’s a horrific story... This is something that goes on with our troops all over the world,' he told The Post.
