I can tell you only one thing: there is nothing you can do to artificially impress this chick. She's been around a lot longer than you, she will be able to see through any act that you put on and will most probably think you're a dick for pulling one. If she already likes you then all you have to do is be cool and let her keep liking you. Be very laid back on this. You won't be in a relationship with her, you'll just be having a good time and enjoying each others company.

Let us know how badly you feck it up.
