Thanks for your log. There are so many parallels in your W's behavior to mine that it's both scary and comforting.
I am finding (slowly) that I still over-think every look and every word (or lack thereof) and read more into it than is probably necessary.
My W still states she is confused about the sitch, but certainly willing to pursue separation of finances and planning for selling the house. It's tough to experience this type of passive-aggressive behavior - especially when the W's perception of the last few years is so different than mine or reality (not sure which).
One statement you made awhile back is: "I have everything to lose, and she has everything to gain. I still feel as though I love her dearly, but I will not cut my head off and hand it over to her on a platter. I think a lot a guys by now would have said 'screw it, I'm out!' and would have pulled the plug and moved on...".
I actually did over-react recently and stated I wanted a divorce from her (no previous D talk, just separation). That statement brought only one tear to her eye, but a couple of days later in our first financial-separation planning session together she stated 'it was moving too fast for her'. I let me guard down for a minute to state that perhaps I jumped too quickly into suggesting a D, and within a few minutes she was taking a shot at me for putting all of the responsibility of the household upon her. I left, frustrated, because it always feels like I'm unwelcome to visit the house.
The cold-warm oscillating kills me every time, but I'm seeing the common patterns among the forum authors, including yourself, and it helps me keep perspective.
