Stop the "hope", your R is gone and W1.0 is dead.
Maybe set a new date and this time ONLY focus on you.
Your improvments and your life. What do you want to do in your new life?
Work towards being ready to file (as Steve said) and if things are still the same when the new date comes, file.

In regards to LH post about D not being the end.
I told the first "non-close" person a few weeks ago what is happening.
She just laughed and said,
"Yeah we also did that after we got married. Then we got back together and had our third" (As in third child)
