When you are gaming a girl who has game herself you need to have a stronger frame than her, pass her shit test by not coming across needy in any way. Show her that you have high value and that it's no big deal for you if she's not hanging around or if you were negging her too much (I think that cocktease-neg was not bad, you shouldn't have apologized! - Only apologize to a girl if you screw up big time, not because of a neg you weren't sure about).
What you can do is meeting her with her friends when going out and show her that YOU are the center of attention. Talk to her friends more than to her, befriend them, even open random sets with openers that are rejection proof (e.g. present for your girlfriend you are now dating for 6 months etc), use preselection, be leader of men...
Kino escalate a lot and constantly push her compliance threshold by some bait-hook-reel-release and reward her for IOIs and "good behaviour"
Good luck out there!
