how can i know this girl is real?

[john]

I met this girl on a chat site an we got talking i went well. I asked for her number she gave it me so i text her then she messaged by the chat and said she has no credit. So i added her on facebook. She has plenty of friends that like her pics but they hidden off profile. Her profile looks real. Anyway we skyped because she asked to we"ve done this a few times and that seems real she nods at questions laughs looks real. However she has started not coming on facebook but we did chat and in middle of conversation she say said "hey handsome guy shall we skype later?" So i said "why the hey?" She said "sup? Hi, hey, hiya which do you prefer" so i said "but have just been talking?" She put "slip of fingers lol" i think she either could be fake or talking to others. Im going to meet her wednesday. Any advice or thoughts? I cant take a friend by the way
