According to @chymaker who shared the story, the man was sent a huge sum of cash which he used as proof of funds which made it easier for him to get his student visa and he, in return, promised to marry her when he came to the UK.
However, after moving to the United Kingdom, the man reneged on his promise and refused to return the cash she had sent him, which he used as proof of funds.
The narrator, @Chymaker said he intends to take up the case if the young man doesn’t refund the lady the money despite breaking her heart.
