Good luck bro. Find what she enjoys doing and then take her to do that. If you never try, you'll never learn. But only in the initial weeks of meeting her! If she likes you then she would tease you, flirt with you, touch you, etc. Follow your gut and use these pointers to help you figure out whether or not she wants to be with you.
Also, her sister half sister and I found a "love letter" to one of my friends, who she later asked out, if this is any use on the matter of whether to let her make the first move or not.
Does SHE like YOU back?
Through your actions and your body language, you've made her feel valued as a human being, and not just as a one night stand. I asked this girl if she likes me and she said she was gay as a joke. Really enjoyed reading it. As far as her moving her body in, that's normal conversation; that's a sign that someone is interested in what you're saying, or so that they can hear you better. Jones, man, it's really no different than grade school, but just on a more "grown-up" level. But, as they say, knowledge is power. Occasionally, you will get rejected.
