See if you can find brandnewday's post b/c she and her h are in piecing but he was gone a long time, if I recall correctly.
Also, I have two relatives who actually divorced (well, their spouses divorced them) and then remarried them later on. IN both their cases, they gave the WAS the space/divorce they sought, after trying to keep things afloat. But the WAS's left and worked out whatever it was they wanted to work out. IN both of those cases, the LBSer also moved on, GAL, improved themeselves as partners, etc and were civil whenever they ran into each other. I think they all had to see each other now and then due to kids, but there was No pursuing by the LBSer as I recall.
Then my uncle called my aunt after seeing her at a family function, and asked about having a drink. They did, and at some point he asked her if she was happier single and she said she was not. My aunt never really spewed at him, nor did she chase him or give him the idea that she was waiting around.
My cousin K, and his wife divorced and had 2 kids. B/C of the kids they'd see each other at some important family functions and K was always civil to his ex-W. He didn't show her a lot of anger but pretty much acted like he was the type of man only a fool would leave. Eventually they'd start talking about safe topics, and that grew into friendship, which lead to their reconciliation. K says their 2nd M is better than the first, and my aunt also said her 2nd M with uncle was better than the first one was. In both cases it was the WAS who made the move to reconcile.
FWIW. j-
