She wants you. Repeat after me... "She wants me"... Now remind yourself of that the next time you talk to her. Get extra flirty and don't be a nervous bitch and shy away, be the one to push it farther. Believe me, it will feel great and it is fun. If she's into you again, she'll eat it up like candy on Vday.
One of two things will happen. 1). You will pee in her butt 2). You will find out that she's just fucking with you because she's bored and really doesn't want to go there again.
Either way you should figure out what's good so you can start walking your path. Godspeed, young padowan.
