burned, aside from this whole file/not file exchange, how often do you have contact via text/email with W?
It doesn't sound like things will immediately settle into a NC situation, but when they do I think this may help. Not NC in the sense that you're punishing her, or withdrawing - but NC in the sense that once you don't have anything to communicate back and forth I think you'll find some more peace. Look forward to that in your future: peace.
Until then, keep doing your best. When in doubt - do nothing.
I've read folks here saying often "Doing nothing IS doing something". I think of it with the phrase from (again - here I go...) my favorite poet..
"Anyone who has sat in Lotus for more than a few seconds knows it takes a h3ll of a lot more muscle to stay than to go" - A. Gibson
Meaning - STAY STILL. That takes a lot of strength. Stillness is your goal. Settle into yourself and your intentions.
