On one hand... what she's saying may not be true. From accounts i've read from other WAS's, they flip their minds a lot. at the time, she may have been sincere in enjoying the time together. yet when she told you she "just wants stuff complete", she may have been telling you what she felt at that second.
On the other hand... it may not matter. words may not change her mind. What some people might suggest, if you want to potentially avoid her filing, or at least shorten recovery time, either for your marriage or just yourself... is to go dark now.
IF she blames you for her being unhappy... see who she blames when you are no longer around. The last memories she has of you two together, were positive (i think?) So going dark at this time, would be good timing, if thats the way you wanted to go, i think. This would have to be a pitch black, "you want me out of your life to 'be happy'? ok, I'm gone. be happy, then. talk to my lawyer if you need anything legal.".
This would be dark for months. probably all the way through november.
ORRRR... you can try to buckle up, and stay on the rollercoaster until her mood swings again.
I'm still on the "i think she's just toying with me, through all the divorce filings" negotiations myself. Getting sick of the lies. When will they learn that lies dont make us happier, but just piss us off more? sigh.
