Expat (m/f) and Gold-digger (m/f) Horror stories

'A gold digger is someone who is more interested in your money than actually being with you in a relationship. It is rather risky to be with a gold digger because you are not only putting your wealth at stake, but you can also expect heartaches along the way because of betrayal and overall lack of love. Even worse is that gold diggers are normally very hard to spot during the relationship. It is because when your intentions are good, you tend not to think evil of another person and put all your trust in him/her...'
