Well, call it DB or going dark or whatever you like, but after our last conversation a week ago, I fundamentally decided that if she really wanted time alone (no calls, no email, no texts, etc), then I would abide by that and spend the time focused on seeing friends I'd fallen out of touch with, concentrating on some work issues, and spending more time focusing on some of my hobbies.
I did send her a very short email telling her that her new personal credit card and bank stuff had arrived in the mail. She suggested a time that I agreed to, then she came over today to get her mail. A lot of people talk about how liberating it felt for them the first time their WAS came over and they were dispassionate and non-emotional about it. I did that, but I have to say, for me, it felt like crap. She asked about what I had been doing with some of our mutual friends, and I gave just a brief account of how we had a good time at dinner the previous night, and that was it. She stood at the door on the way out looking sad and like she wanted me to start talking, but I just indicated the mail, asked if this was all she wanted, and that was that.
It felt terrible to basically turn her out of our home like that, but I didn't want to cry and beg again because (a) she said explicitly she didn't want to; (b) I feel like crap now, but I imagine I would have felt a lot more crappy if I had gone the other route, and (c) some dark cruel vindictive corner of myself wants to say (but obviously didn't) "You wanted to be alone, and now you start to see how miserable that road is. Tough stuff, huh?"
