Is she playing hard to get on facebook?

[Alcatraz]

There is this girl in school that is 1 year older than me. We are at different floors with different friends.
We have seen eachother at the gym and maybe on the street once.
At school once i said Hi but later ran off for a class and looked like a pansy.
Since i couldnt find her out of her classroom, i decided to add her on Facebook.
Now we chatted a little bit but she didnt seem to interested in chatting.
At one point she looks shy but deep inside a badass (just like me). So i dont think she is hiding her "love" .

Now my problem is should i ask her to go somewhere or is she not interested? Could she just be shy?
