there's a trail a mile wide of lonely hearts, who have been scammed, and most said exactly what you have said, it won't happen to me, sadly it does.
As others have said why would anyone who is rich, firstly advertise that fact, most don't, certainly not to a complete stranger, unless a walter mitty, living a double life. Meet by all means if that is what you really want, but i wouldn't accept anything but a drink.
