Unfortunately scamming by Filipinas on dating sites seems to be rife now....especially by the ones who state that they are 'students'.
It's a racket that is catching on fast.
Yes of course there are millions of genuine nice ladies waiting to meet you too, but putting your sensible head on is a MUST.
Why would anyone send money to someone they've never even met, and to someone who may not even be the person they purport to be ?
You've fallen in love with the idea of being with this gorgeous person. You're acting like a lovesick schoolboy, and you're not thinking straight. Get a grip !
It's quite easy to judge whether they're scamming you or not....IF you read between the lines, and bother to learn something about Filipino culture.
Go to the Phils, meet the lady and treat it as a normal relationship. If you can't do that, or have no intention of doing that, then don't bother corresponding with her at all...not fair to lead her/them on.
