So it seems like you did a decent job building enough attraction and comfort to k-close her, which is great... good job.
It doesn't seem like you gave her a time constraint though, which is clutch if you want to get in her
. Instead of staying up with her till 2am you should have cut it off way sooner.
I wont say any 'you should have done..'s' so i'll just advise you for next time, make sure to keep time restraints.. you got one step ahead by kissing her, its time to take a step back. Tell her you're busy and need to do something important (make it seem more important than her) then.. tell her you'll call her tomorrow.. Give it two days then text her or something..
Time constraints man... key!
let me know how you feel about this reply
