Oh man, i'm so sick of reading these AFC questions... Sorry, but it seems to me you still don't understand the art yet...
I'm guessing you haven't read the HS Bible, or the normal DJ Bible...
Mate, read them, then post, cause this sounds like a stupid question to me.
But, since i am a nice guy, i'll answer it for you.
1. She is trying to provoke an reaction from you. A sh!t test is her doing something and judging your reaction.
My advice: Don't give a damn.
2. You're wrong, she isn't as into you as you think you are, i think this is a pretty good bet, since it seems to me you haven't got some of the most basic but critical concepts, or you wouldn't have posted this.
My Advice: Go read the bibile.
3. You are thinking about it too much, soon, even if you don't realise it, you will start to convey neediness through your tone of voice, the things you speak, and your body language. Loosen up, and be confident.
My advice: Go game other chicks.
By the way, girls won't restrict themselves to you, not when you 'think' she likes you, she's just pretend boxing... This is a pretty AFC post to be honest...
Sorry.
Good luck, keep in mind what i said, make sure you go read the bible.
