Avoiding the Friend Zone...:( Care to much about her?

[Richard]

So, a couple weeks ago I met this girl. It was her, a friend and me, we had supper and went to a movie. Befriended her on Facebook and then started chatting. We chatted of and on in the beginning, I'd usually start a conversation every 3 days or so. Then, after about a week she started most of the conversations and now it's like a non stop conversation, we're not constantly texting but we more or less continue most of the day. So with the holidays we've been to busy to meet up again but we'll be at the same party next week. We sometimes are a bit flirty so to be honest, I can't imagine she doesn't know I like her. I also talked with her best friend who told me she hasn't spoken to her since that time (I know this is true and know she is not just avoiding to tell me she doesn't like me), so she doesn't know how she feels but she feels sure that the girl suspects the fact that I like her. I've been friend zoned before and really want to avoid that again... Thanks!
