Divorce not busted 2

[Orich]

I think I'm in a gray area for DBing, unless I don't understand it fully. Let me explain:
I wrote about the letter she sent and how final it was. Then she texted me that she regretted the letter. Between those times, I was avoiding her and barely talking to her, and as much as I tried to hide it, was visibly upset. Not crying or yelling, but not my usual self. After the regret text, I warmed a little. I spoke to her more, didn't leave the house as much. At first, she seemed receptive, now she is withdrawing again, and even apparently avoiding me.
Now, do I get all cold and avoid her and not speak to her as much as possible again, or do I maintain communication, even if she seems unresponsive? Is she waiting for me to do or say something? Should I bring up the R again? We will be together this weekend doing stuff with the kids, you'll recall in her text to me she said she would rather be with us doing fun stuff together rather than go away.
Not sure what to do here, looking for some advice. And BTW, I am not looking for ML right now, it's not about that. God knows the lack of intimacy has me crawling up the walls, but I don't see it even being the slightest bit of a possibility right now. I just want to re-connect with W.
Thanks.
