There's a girl I've been into since I met her about a month and a half ago. We see each other frequently, as we go to grad school together.

I feel like I've made it really obvious that I'm interested, although I haven't told her yet. I've still been feeling her out for signals; basically, her behavior portrays interest but her body language doesn't, it feels like there's zero invitation to make a move. We've been hanging out more and more, have shifted from just seeing each other at group functions to seeing each other one-on-one, but I'm in an utter state of confusion to how she sees me. She's an insanely hard worker and hardly gets her nose out of the books it seems, and when she does it seems like she spends as much or more time with me than she does with anyone.

Two basic questions...
1. If a girl realizes you're interested in being more than friends, and she doesn't return that interest, will she usually distance herself a bit? Or do most girls who care about the guy as a friend not really care to distance themselves regardless of what they think the guy is after?

2. My go-to female friend informs me that she has found it creepy when guys she views as friends have told her that they see her as more (she was referring to her single days, she's married now). As such, she has cautioned me against just coming out and telling this girl what I think of her. Is this a majority opinion among girls? "Creepy" sure seems like a harsh way to describe a guy being straightforward and honest; I understand that it could be creepy for a guy they see as a friend to make a move physically, but just saying what they feel? I'd be interested in more opinions on this.
