I have not read your whole thread so forgive me if I miss an important detail.
But my 3 questions and 2 comments are semi universal, so here they are:
1) do you have a DB coach? I found them to be true Godsends that can help you clear your mind and keep the path in your head a lot clearer too. MY DB coach was absolutely the woman I needed advising me at the hardest time of my marriage. The DB coaches are cheaper than divorce, and when added up in a package their costs are comparable to others therapists (who don't take insurance)
2) what are the issues your wife would say are YOURS to work on? IOW, what would She say was wrong with the marriage, and what of those things are you working on?
3) along those same lines, what are the 180s you are doing, that may trigger some 2nd guessing on her end,( which we want!) to counter the negatives she's using to justify leaving?
Bottom line is this: NO WAW will return to the marriage she left
UNLESS---
she believes the marriage can be better/different than before.
How are YOU demonstrating that to her?
And finally, here's the "math" of it: consistent change + sufficient time = change she can believe in.
