Just met this amazing girl online?

[420]

About a week ago, I got a friend request on Facebook. This girl, who happened to be an 18-year old model (I'm a junior in high school), sent me a friend request and I accepted. I started to look at her profile and said 'hey' to her just to be friendly. Well we would respond to each other but yesterday and today we really talked. All of a sudden I felt really comfortable with her. She said she doesn't mind talking about me and she said 'I wish all guys were like you.' I would complement her on her beauty and she would frequently say 'aww thanks <3' and 'you're so sweet'. Also she was concerned with my questions. Over the past couple days, we really became comfortable with each other, using smiley and faces and using hearts. The problem is she lives thousands of miles away and we'll probably never see each other face-to-face. But we've said if we were close, we would hang out to get to know each other better. It's amazing how she has the same thought process as me, being concerned with others and such. Also she appreciates how I act like a gentleman and always support and wish her luck for her career, success and model shoots. She has said that I am like the perfect guy. We would talk normally like what we are doing or where we would go if we would go to a other continent. She called me amazing today and she started sending kissy winky faces as well.

What should I do? You think she's real or fake? How do I detect if she's real or not?
You think these feelings are for real?
