Date set 8 days out, and bad communication. No real connection.
Radio silence, with just a confirmation the day before, is very poor game. Expect her to be unenthused and likely flake.
2 quick tips from my view:
1. All women mirror. From English to Polish, to South-African, to Italian. From 20 to 30. Doesn't matter. Just seems to be a general woman thing. I've found it constant to deal with.
I don't think it's good to mirror back. If I don't reply to something in 2 hours (genuinly), and she mirrors, I don't mirror her mirror. I consider that overgaming.
2. Be a bit wary of how momentum effects your sets. Wise man once wrote:
There is a tide in the affairs of men, Which taken at the flood, leads on to fortune. Omitted, all the voyage of their life is bound in shallows and in miseries. On such a full sea are we now afloat. And we must take the current when it serves, or lose our ventures.
