So I asked an HB8 on a group "outing" with my best friend and his girlfriend (who shes good friends with, and will be driving her) recently. She accepted and gave an IOI - saying she was really looking forward to it.

Should I try to isolate her/how would I go about that?
or
Should I keep her in the group and just have fun as a group?
or
Combination of the both, how would I go about isolating her in the group?

Why not isolate her? Would you be embarrassed to drag her away from the conversation to show her something cool for a second? Would it bother you or anyone else if you say, "Hey, come here really quick. I want to talk to you! " Or maybe just get her to turn her back to the group for a second (mini-isolation), and tell her that you love how her earrings match her eyes/ her shoes match her dress/ her sense of style is fantastic/anything but a biological compliment. Don't worry. Just take your opportunities as they come, and remember "ease and delight" - Zan.

Good Luck!

something else you could try is , talk to your best friend before hand and come up with a plan for him to find an excuse to pull his gf aside. this will give you the time alone with the girl your interested in without you having to come up with a way to isolate her on your own. its sort of the same idea as using a wingman to distract an obstacle.
