Hmmm ... sounds to me like she has never really been that into you. (sorry if I'm being harsh, I'm not trying to hurt you or anything) I seriously doubt if she'll end up looking at this the way you do. Even if you get into a relationship that would give her an immense power over you.
Now, over to the constructive side
If you really want to make an impression, you need to so something that touches
her. What this is I cannot know (nor can anyone else here) since I don't know the girl. Just try and think about what she has told you she likes. Don't be afraid to make a fool of yourself. And maybe if you post some info about her there might be some help in finding out what you can do as well
