Don't really post on here much anymore but thought I'd have a gander to see what you lot were up to.
Just spent the weekend with Tom T in Sydney (sounds romantic, it wasn't you dirty bastards). From what you've said it sounds like you're doing the one thing you absolutely mustn't do in your interactions and that's hiding your dick. Tom says this is one of the biggest failings in his students i.e. you're doing 'nice guy' daygame, which may get you the odd number but it's not going to get you laid, hence the flakes.
I'm still far too nice sometimes in my interactions and yeah the conversation might last longer, but it's not conducive to creating the sexual tension needed for her to want to reply to your texts.
Focus on throwing in a tease after your initial compliment i.e. a push immediately after the pull and like the others have said, you need to be throwing in spikes throughout (there's loads of posts on this).
The old daygame model is a bit dated now. Focus on Open - Attraction - Vibe - Invest - Close e.g. open with compliment laced with a tease, stack into an assumption to generate a topic then use the topic to riff with playful push/pull, challenges etc until you reach the hook point. Then you can have a normal conversation to bed it down a bit then close strongly.
Keep up the good work and good luck mate.
