How to get out of the friend zone?

So like a month ago I started talking to this girl that I've known for a while. We were never the best of friends but I did talk to her. She found out who I liked and gave me relationship advice that I didn't really want. A week later after talking to her everyday she asked me for relationship advice. She told me what happened and I told her he was using her (cause he was) and she said that's what she thought. Everyday since then she talks to me and asks me to hang out (but we haven't yet). Yesterday I said can I ask you a question (I was making a joke) and she said yes you're my brother. She has been pushing that and has told me a million times I'm her best guy friend. I don't know what to do. All my friends and hers say stuff like are you two dating yet jokingly and say stupid things like that. Back when I gave her the advice I never really thought of me liking her so I just gave her the advice.
