You seem to be doing well dude, I usually mirror the girl in early stages. So I'd say you're doing alright there.

Something to remember though is that texts between first meet/day2 is there to keep her warm and build comfort, so be very careful with C&F, use it, but make sure it's obvious. I've had girls stop responding after taking a to harsh C&F as serious.

I reckon you should not try to get her to call you, but just call her, let her know you're going to do XXXX and if she wants she can tag along. That way she is entering your reality, not being asked out.

Seeing as this is an Ex of yours, would you be comfortable escalating sexually? For instance if you had amazing make up sex, or a funny position you enjoyed together etc. Remind her of it, it'll put her and you in a sexual frame in her mind.

Example:
We should never get together again, those arguments use to drive me insane! The make up sex was fantastic though....ok need cold shower now! xx
