If I were in your situation heres what I would do:
Next time you're around her act normal. Do what youve been doing. You've negged her plenty so Id keep that light. When you do neg, smile and give her some light kino (pat on back of arm for example). Once she starts giving you the IOIs, after say the 3rd...Isolate!.
Hey lets chat over here for a sec. Excuse the two of you from the group.
Since youve been noticing her Interest in you not only tonight but several other occations be direct.
Something like:
"I'm gonna go get coffee at (Place) , tomorrow before I ( visit my parents / run errands / help my roomate w/ the theory of relativity / cure for cancer / activity in which youre DHV). Stop by and try their (coffee drink / or tea ) w/ me.
She'll answer....If she doesn't suggest a # exchange, just take out your phone and give it to her. She better know what that means. If not I'd say.
"Yea if you hold it long enough, itll turn into a pink elephant that'll take you to clue castle, Then you'd have to figureout how to get ahold of me so I can come rescue you....geeez." Then smile.
There should be a #close. After that playfully neg her, Kino esc. Play push her.
Make some some talk, throw in a DHV story for good measure.
(I say DHV in this situation so that way she wont feel like u got what u wanted and ur done w/ her. Also raises ur value and more incentive for her to call.)
Ok lets get back to our friends.
thats my 2 cents
JUSTINcredible!
