I wish I had some advice worth sharing, dday. Again, my W indicated that she will likely be filing before the end of the year. Could be Dec or even Jan she said. Knowing her, she could change her mind at any moment and do it sooner which is why I'm holding off on the pressure.
So I'm getting myself mentally and emotionally ready to handle receiving papers while being prepared to take any opportunity to validate her whenever we might talk again.
The one thing that's helping me is that our sitch got so bad over the summer, and she's done me that way enough times, that I have no desire to go back to that. So if she refuses to commit and the best I can expect is more of the same, then I'm good with moving on.
