These are all very useful comments indeed. To robx: W has initiated a separartion. We've been living apart in the house since d-day & she's moving out in June after kids's school yr ends.
On the food thing, that was all 180- the boring old housedad me she's divorcing would never have thought something through like that. So yeah -I was doing some impressing to be sure, but by the same token I really liked the result & ift's something that I can add to my dating repertoire when W moves out. (Assuming I take her up on her invitation to date OW to my heart's content, of course. But even if I don't, it'll be a nice thing for courting the next ex-Mrs. SP.
To DanceQueen: you may well be right. Overthinkingly, what strikes me is (a) the timing and (b) the move itself, which I've never seen her do in 22 years. Let me just say as a personal aside, DQ, you seem like an awfully cool Lady & I'm glad you check in on my thread from time-to-time.
To GFI, I fully agree that labels are only temporary salves. I'm just curious to know is all.
