The Church and the girl

So, I recently found direction in life by salvation through Christ, all thanks to a girl from my past. Not much I can really say about her, other than I still have the same feelings for her that I did back in 5th grade when I met her. I spent all summer basically doing as much as I could to be around her, volunteering and attending regular services. She's amazing, doing so much and still having time for college. She considers me a great friend, she has said so. I really want to be with her, and considering my feelings for her haven't changed over the last eleven years, I know they are never going to change. Now, I just ned to find the right timing to ask her out. I think with her, that big romantic gesture would work, but it's not my style. I just want to do everything that I can to let her know how much she means to me, every moment that I am around her or talk to her. Anything I can do to make her smile, I'll do it, just to see that smile. Still, I have no idea how to ask her out or when the right time is, so each time I am around her I get butterflies in my stomach and still stumble around words talking to her. I wish I knew what to do...
