For future reference, unless you know that she likes being put on the spot like that, never make an embarassing public pronouncement of your feelings like that. I know for me, if I'm put in that situation my response is more about stopping being the center of attention and being angry that someone would put me in that position than it is about whether I like the poor guy or not. My feelings and personal life are not something I discuss in public, ever.
So my advice is to write to her, apologize for the way you put her on the spot like that, and ask for her to give you a chance at just 1 date to see if the two of you can hit it off. And if she says no, mourn the loss of all those hopes and dreams, trust that God (and quite possibly this gal too if she's as wonderful as you think she is) is watching out for you and sparing you even worse heartache, and then let it go and move on with your life. There's really nothing else you can do. Going all stalker on a girl never won her heart; it'll just drive her further away.
