Its not a surprise your W is spinning about the L .... again its pressure and if its one thing that makes the doors come off the hinges with these MLCrs its pressure ... and yeah .. your W is MLC I believe.
So she bounces back and forth in her own fog, pulling at you making sure you are there for her regardless of where she is emotionally for you.
My W would TM at all times of the night, like you I would pick my spots on when to reply .. at first I was all over the place then I started replying when I was emotionally equipped to handle it. Spew flew .. it was similar to 'you call all the shots, always your way .. .I have never had a voice in this" One day I had my quiver full of truth darts and basically tore those myths to shreads, I validated that I was sorry she felt that way not angry but more of a father "Enough is enough" type tone and pointed out that she in fact was the one who was spoiled and has always had it her way, but now that I am GALing and its not what she dreamed it would be ... she throws a fit. Well ... guess what I am not your H, you fired me, so I have landed a new job at "Cali will survive regardless.com" and I will do my best for myself and S and move on with my life that you no longer have a part in, again ... her choice not mine.
Hang in there, do not get emotionally drawn in as she is pulling out the big guns ... the kiddos... keep focused and stay the course.
