What do you guys say ?
There is this very good looking ex co worker of mine, we have gotten intimate before at a club but nothing more.
After i left work, i initiated a conversation and she set up a coffee date, which she later flaked on.
Anyway i have been sending some experimental PUA texts, (outlandish) bullshit stuff really, just as an experiment, and she has begun by initiating interest by liking stuff on Facebook etc.

Question is, should i let flakes be flakes and ignore them, or should i mess around a bit and do some experimenting, and if so what would be a good way to experiment on a flake.
Im talking about pushing and pulling techniques, negs etc, just fun PUA stuff.
