<human>: Can you give me a shortened version of the text?

So I'm like 95% sure my crush really likes me and wants to get physically close(kissing), and maybe date me. She told me when we were texting that I was the best looking and the sweetest guy from our class, but hasn't told me if she is interested in anything. (In Denmark you are in the same class with the same people through 10 years of school.) She told me there was a guy from our klass she wouldn't mind kissing with, and was like quite sure she would like a relationship too. I'm like 97% sure the first one is me, but I don't know about the relationship.. 

But, before I ask her on a date and tell her about my fellings, I would really like to try and kiss her, so here's is my question:

(This would have to be at a party) So say we're just talking and I put my hand on her leg or my arm around her shoulder, if she is interested in kissing me too how will she react? And if she is not interested, how then? She is also my best girl friend, so I really don't want to mess this up, and I want to be sure she wanna kiss me too :))
<bot>: How do I approach my crush, who I am really sure likes me too, at a party, if I wanna kiss her, and how will she react if she wanna kiss too, and if not?
