Basically I met this girl at a mates party yesterday. During this party, I talked to her and expressed my interest in her by telling her how unique and exotic she was (halfie), and I wanted her number. While she was hesitant at first, I used the technique of "prizing"(mentioned on this site), leaving her to talk to the other boys so that I dont seem desperate and making her "prize" me. Eventually she took my phone while i was away and place her number in it. Later that night while everybody was staying up, she rested on my shoulders sideways while I whispered in her ear that she was the most beautiful girl I know.
However, while I was about to leave(I havent talked to her for about 1hr since this), I briefly hugged her and gave her the customary kiss on the cheek, said "ill miss you" and left promptly. It happened really quick and didnt seem affectionate because I had to rush somewhere.
MY QUESTION IS: Was that too brief? I've got her number in my phone now and she seems to be commenting on photos of me and my friend on fb, but I dont know if I should go talk to her immediately, wait it out or play hard to get. What should I do now? Any advice is GREATLY APPRECIATED.
