Well, I know what you mean, but part of me feels like I didn't stand up to her feelings, I instead avoided them. I did have fun with my kids, it was after they were in bed when the intensity amped up.
I agree with listening to actions and not words. If she wants to talk she will start a conversation and I will acknowledge her feelings, tell her that I know she has no interest in working on our problems and I will not fight her on that anymore.
The place where I will stand firm is when discussing the future of our kids. What might a schedule look like if I agree to a trial S? How can we minimize the inevitable damage that will be caused? My W will have to know that life will be VERY different after a S. I will not leave until we have worked something out that is in the best interests of the kids and we lower their anxieties.
