Shaggy - From that transcript, it's no wonder why you don't have a girl. You're mean.
Now, do this...tell her you got some money, if she asks how, make up something like, by turning tricks. Then say you are going to buy her a plane ticket, but directly. Where you either mail her the plane ticket or she picks it up at the counter. The only person that could possibly get money for the ticket would be you, so a scammer wouldn't like that. But it's a reasonable thing to do if you weren't dealing with a scammer...see if she has a problem with that.
BTW - If she comes to the US, with the intent of marriage, and doesn't come on a fiance visa, I think you two love birds will have problems. So bring that up and see what she has to say.
