Question about a girl?

ok this will probably be confusing but i hung out with a girl last week and we had fun. she said she loved talking to me and was glad to share the night with me. she also called a guy friend. anyways we both are interested in similar stuff. she has an obsessive personality like me. she told me a personal secret bc she said she trusted me. she almost always returns my messages to her and she asked that we talk online alot. does this sound like just a friendship because im very confused. she invited me to come and stay with her at school but i dont know if its strictly platonic. would a girl talk like this to a guy if she just saw him as a friend, ladies?
