AnotherStander, thanks for your comments two weeks ago (I'm bad at visiting here more frequently). It's nice to hear that others have had the same experiences (or are still having the same experiences). My ex continues to extend herself but still oscillates including suggesting from time to time, in subtle ways, that the kids are happier now than before. I don't buy it for a second and feel as though she's trying to convince herself as much as me, but I don't engage, usually just acknowledge the suggestion, and always resist the urge to say anything to remind her that all kids would be immeasurably happier with both parents in their lives on a full-time basis.

And thanks for suggesting Married Man's Sex Life Primer, some interesting reading there it seems, especially the part about type and trying to find another you. I was able to find an excerpt online but have now ordered the book from Amazon.
