I met this HB 8.5 the other day we exchanged numbers and texted each other and sent up a date for this weekend (we're gonna chill at my house, watch a movie, smoke a little weed). But the thing is, is that I got a half-ass answer "Idk if I can, but I'll let you know" usually in my experience when they say something along those lines they usually end up flaking. Since girls flaking is a common aspect of P.U I did some reading to try to figure out a way I could use this to my advantage and came up with two options either A I wait for her to flake, pretend I never got the message, then text her the next day and act as if I was the one who flaked on her or B I beat her to the punch and flake on her before she flakes on me (already thought ahead and have back up plans). So would it better to wait for her to flake and me just spin it around and act as if I was the one who flaked or should I beat her to the punch and flake on her instead?

I would go with option A, since it has more finesse to it.

I'd go with option C, myself:

C: Don't worry about it until she actually flakes, then next her if/when she does. Her loss.
