Karlo,
It's a little bit scary to meet someone online. You just don't know what kind of person you'll be dealing with. So I advise you to be very careful. Ask about the person's full name, her address, and her birthday. Then you can obtain a thorough background check through the internet by paying a fee. It's better to spend some money before meeting the person face to face. You just don't know her criminal record, how many times she has been married, where she lived before etc.
I hope you'll take it easy.
