Are you sure she likes you? Sometimes guys like you confuse friendship with something else. I say do the eye test.

One day when you two are talking, look into her eyes and don't blink. And PLEASE PLEASE PLEASE PLEASE...don't look away before she does.

You're not her type if:

1. she holds eye contact, but then asks "what?" with a puzzled look on her face.
2. she doesn't hold eye contact with you and keeps acting as if you didn't try to look into her eyes.

She is into you if:

1. she makes eye contact, but looks away one second later, but then looks back into your eyes for another second only to look away again. Well, you get the message, she wants to make eye contact, but she is hesitant.
2. she makes eye contact and holds it, and she keeps on looking into your eyes even after she is done talking and both of you are just looking at each other without saying a thing.

If she is into you, then I say try to go after her; she won't care of your status. If she is not, then she probably just wants to be your friend.

I hope this helps you. Good luck.
