Is she wanting me to talk to her or leave her alone?

Hard telling. I hate that kind of stuff too. I say to just talk to her. She could be completely nervous, or confused. Or she could be freaked out. There's only one way to find out though. Confront her with what you're feeling, and find out her position on the whole situation. If she seems too put off to carry on a conversation, let that be a solid warning sign, and don't waste any more of your time. Otherwise it's just going to snowball into a giant mess of awkwardness.
