Your last sentence is very important (while I can relate to all you wrote there), as it is therefore that you/we have to fully detach and work on ourselves with expectation = 0 on a future possible R with WAW/H/S.
It is THE hardest thing to do right, and as sooner as you really start the better it will be. Be also careful not to take positive signals/interactions after some weeks or months or so, as the sign that all is/will be well again very soon. Those are just positive snapshots/moment and nothing more, unless she start talking about possible R without you ever having mentioned anything. I have fallen into that mistake some weeks ago.
