Yes, I'm getting a similar sort of vibe too! Maybe, it's a polite way of distancing herself to avoid any unwanted attention...or perhaps she's in an equal conundrum over your feelings too?
In theory it would be a good idea to just *blurt* out all your feelings but it really does put her on the spot. Imagine if she has only just consider the possibility of "you"...could be quite overwhelming!
Also, (your advice being much appreciated ltj5253) I think it is possible to make a transition from friends to more...perhaps it's even preferable as you know what to expect from each other (likes, dislikes, common interests etc).
