hey guys , i am still a newbie here , joined only a couple of days ago. so after readign the game by Style and watching Mysterys video from youtube i decided to practice some stuff out. me and my debate team had a party in a bar , and the bar was only for us ,it was a small room. the girls there just joined our team so i was maybe on " hi " with some of team , didnt know alot of them. used openers , used DHV stories and got some heavy kino from 6 girls. played it cool , teased nagged ( natural in these 2 stuff ) . and then i tried on one girl in isolation ( the one i liked mroe the the other ones ) the question " what do you have besides your looks " , she responded ( lame responses ) so i thought i was in A3 , but when we went to the club ( i enetered with 5 girls , social proof ) she kind of went cold. she was a bit sick from the booze she drank , but still she gave me alot of kino and ofc alot of shit test which i all , in my opinion passed , but like i couldnt get any further.
i tried taking her o the dance floor ( learned valzer for a year ) so i tried dancing with her but she kind of jsut turned around so i excused myself and went to dance with another girl . after that she again gave me heavy kino , i tried to isolate , it was unsuccesful. i properly froze her out when it was needed , but still didnt get me anywhere with that girl. eventually she left home wtihout like any goodbye. oh yeah and she asked me 5 times in the disco " have you seen my friend lea" dont know if that means aynthign , i didnt gave her and straight responses , tried to make it funny. i went home alone , but got the numbers of 3 other girls , and a kiss from the 4th one on the dance floor , but the one that got away bugges me .
i did make some mistakes in the bar , like not turned my body toward her after 30 sec of talking and maybe throwing a neg or two extra ( playful way thought , she smilled alot and hugged me even more ).

any constructive response is welcome
btw i am 20 , live in a bit conservative town with a 100 k population in eastern europe , balkan region

Not everyone will like you. If you did everything right she still might not like you. And if you think you did some things wrong, try to correct that next time. Don't worry about the ones that slip through your fingers.
