Close friend doesn't want to date but behaves like we are dating?

My closest friend right now has told me outright that she doesn’t want to date me though she won’t say that we’ll never date. We went camping together this past weekend and she behaved as if we were together. There was so much affectionation, sharing and connection it made for an amazing time for both of us. Getting back, she commented that she laughed too much and thanked me multiple times for a great time. This girl is clearly deeply emotionally attached to me and loves feeling that closeness but doesn’t want to commit. What should my course of action be? I do love her a whole lot but I’m not sure if she’ll finally warm up to the idea of dating me or if this is an impossible pursuit. I would love any suggestions that you could offer.
