I would back off on pressing her right now, unless you are at a point where you want to do the ultimatum thing. Just have to be willing to live with the answer.
I am certainly no expert like the others you have named. But, I would give her space and time. Her having pull backs is normal. That's the hot and cold. Take a look at another thread I started in the piecing forum and Hope4us' posts:
I suspect if you push her, you will not like what she says. But, if you are ok with her response, that's your call.
Keep up your GAL'ing, especially this week while she and the kids are out of town. Hook up with some friends and head out at night. Flirt some. It will help your self confidence. Personally, I try to flirt anytime I get the chance now, but I will not act on it while I'm still M'd. I know others may differ with that opinion, but it's just not me to cheat.
As for her calls this week, I would just play it like the prior conversation about what she and you want did not occur. If she wants to bring it up, then let her be the one to do it.
