Friend crush or more?

I met this girl through a mutual friend. She was warm and friendly from the beginning and we eased into our friendship quite nicely. What started out as genuine interest is now bordering on infatuation. When I first met her , I thought we would be really good friends, but a lot has happened since then, and I haven't gotten a chance to really know her, or spend a good amount of time with her. I don't want this 'obsession' to ruin the chance of establishing an actual connection with her, yet I dream about holding her hand(literally had a dream about this a few days ago), and making her smile, and buying her gifts....is this a crush? Am I exaggerating by labeling it an 'obsession'? I think about her almost everyday. I would talk to her but she's not the best texter(neither am I). I asked her if she wanted to hangout(explicitly a friendly hangout)and she said yes, and now I'm incredibly nervous because this would be the first time we're hanging out just the two of us(we belong to different friend groups so most hangouts together have been within a group). I don't want to ruin this. I have this intense need to know everything about her, to understand her, to get a glimpse of her world. She's been making an effort to get to know me, I've just been too wrapped up in my own issues to give her my full attention. How do I go about this without ruining everything.
