Whats some good lines to isolate girls when you are in a small group? For example, last night I was hitting on a very cute blonde girl all night and she was totally responding. Grabbing my arm, squeezing when I said something funny, laughing at all my jokes.... You get jist. But she was staying with her friend and eventually we got back to the friends place until it was just us 3. The friend wasn't leaving and I didn't know how to isolate just the girl with the friend in the room. I got her number and will pursue it. Any future advice?
