i think it happens everywhere and to anyone who easily trust anyone they met online..the best thing to do if anyone is in this situation is to be intelligent/wise enough..we can easily tell if the persons is just after money..having lots of allibis could be one..suddenly disappear and will show up after a couple of months?...well, its already a sign of cheating..she may have found someone on the net aside from you then realize that you were better than him..just stay away people from those kind of drama..
