<human>: Can you give me a shortened version of the text?

So basically I have known this girl(19) since high school but we never really hung out. We are now at the same college and have been spending a little more time together. She told me almost her whole life story in like 2 hours of non-stop talk the second time we hung out (which we have only done 3 times). We are usually alone when together and hold conversations very well. We have a ridiculous amount of things in common and we don't really text but when we do I always text first and always have something for us to do. She's kind of a hippy and "likes my energy" and is always saying how if I ever need someone to talk to that she is always there. I am a pretty shy person and really don't flirt unless she does, but she doesn't.

 The issue I am having is that I have no idea if she is interested in me as more than just a friend. I was thinking about being upfront with her the next time we are together but have no clue what I should say. So how should I tell this girl that I really like her and want to spend more time with her but not as friends? Or should i just say nothing but keep hanging out.
<bot>: I really like this girl I've known since high school. How do I tell her I want to keep hanging out but not as just friends.
