Guys my english is not so good, but i hope you can understand what i mean

So last night i went out on a nightclub with my friends, i was a little bit typsi so i started approaching sets.( when i'm typsi, i can easy approach sets)
I saw my friends talking to a HB9, i started negging her that she looked like she was addicted to sunbathing and she answered with, they call it natural
I knew that was a bitch shield so i kept on negging, just to look like if i wasn't interested in her. So i said, you think i believe you? but i don't remember the rest of our conversation, but she gave me iOi's because i think i was the only guy that negged her, and in the middle of the conversation i went to another girl to talk to ( i number closed that one btw)
My friend sayd the next day that i did make a big mistake because i went to the other girl. Did i negged this HB9 to much or what did i do wrong?
And the rest of the night i opened sets in the beginning when i negged them they gave me some iOi's but they always had to leave, what did i do wrong?

And again. Sorry for my bad english, i hope u did understand

why would you game a girl your friend is talking to?

And personally, I think you lack confidence, so you use neg.

I think you should work on your inner game more. If you can only approach sets like you did after drinking, it says you're beta when you're sober. Also, there's nothing wrong with negging unless she gets legitimately offended or if she stops shooting you ioi's, in which case, you should shoot her an ioi or two to balance it out. As for talking to other girls in front of her, it's not bad because it'll create a jealousy plot-line, which usually helps you get laid if done correctly.
