Just Friends?

I'm not sure whether to pursue or step back and stay neutral. I have recently rekindled an interest in one of my good friends...but she is just that right now...a good friend. I don't want to do anything that might jeprodize that friendship. I also...taking advice given to me by this very girl in the past...need to know one way or the other to help me move on, or if everything worked out expressed a mutual feeling. I hesitate to move forward because I care about her...does she need the friend, or would it be ok to be the boyfriend. If she doesn't reciprocate the feelings...have I destroyed any friendship bond for the future? God grant me patience and to be exact in my wording that I may follow your vocation laid out for me.
