I'd go with the ask her for a Day 2 thing. Bringing up a past experience sounds weird after what she's just said.
I'd say something like:
Girl - Hey Desh wanna hang out this march break ? I havent seen you since Mikes birthday
(IOI)
Desh- Im quite the busy man lol, but im sure i could fit u in my schedule
(Rewards interest with attention + DHV with C&F)
Girl - Bitch. All i gotta say lol i missss you like fuck.
(Qualifies herself without even being tested - Huge IOI)
Desh - I'll be swinging by town tomorrow to do something of high value. Want to grab a coffee when i'm done?
(Rewards with attention + day 2, but doesn't come off too needy. Plus the DHV from the activity of value you'll be doing)
Insert activity of high value & your golden.
