What does she want?

We have been friends for eight years, and we have become close friends over the last few months. I told her I liked her and how much she means to me a few times last year. Our friendship grew as a result because I did not want to date then. I told her last night by email that I am considering dating her. She replied by saying she was working on the longest email for me, but our emails have become much longer lately. She gets nervous around me in person, but our emails are very intimate! Our eyes connect, we play footsie, and we can talk forever!
