Search Results: having courage

There is a girl I like who I recently friended on Facebook. I know her from school, we are cordial, we say hi, etc. There is a two year age difference (18 vs almost 16), but I would say we are of similar maturity and only one grade apart. We have had daily discussions on Facebook chat, I have started most of them. She responds, asks questions, like a normal conversion. I don't know why, but she often leaves the conversion first most of the time. She does not have a phone, she uses a shared computer. She smiles at me, though I don't have the confidence to talk to her much in public, especially with my sister's around. I have known her for several years, though only recently having the courage to talk too her much. I would talk to her in person if we were not in a big group where I would feel uncomfortable. Neither of us have dated anyone. I have caught her looking at me a few times from a distance.

My question (s) are:
1. should I stop initiating the messages?
2. Is she interested in me?
3. Am I pestering her? (I am a good typist, 110wpm, it doesn't take for me to fill the chat box). I also like talking, although in private.
4. Is not talking to her much in public a sign of weakness?
5. Do I tell her I like her or ask her out first?
6. Do I ask her parents to take her out casually?
7. Do I ask her parents at all?
8. Should I ask her friends what they think?

Thanks!
