So what do you want to do about meeting her? Never mind, I know what you want to do, but it would be the wrong move.
I would imagine she wants to do what we call a "temperature check" to make sure you are still strongly attached to her and will jump when she says frog. She's probably wondering what you've been doing that has had you so busy that you've gone five days without finding a reason to contact her. The curiosity must be eating her alive. That's good. Like the book says, be mysterious.
My suggestion would be to text her back and say, "Thanks, but I will have to take a rain check". If she starts with the nosie questions, just text back one time and say something like, "Sorry, but can't talk at the moment. Have a good week with the kids".
Youphase created a different type of opportunity. It is called "being less available to her". Remember reading about it? Do not drop everything and run when she crooks her finger. She will be more interested if she thinks you are pulling away.
Now, find something to do.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
