Haven't commented much, but been keeping up with your thread. I read [edited by dbmod: reference not recommended nor allowed] a while ago and it really changed a lot about me. it truly is ironic that all these years she wanted me to be more assertive. I make sure she always knows when I don't agree with something, or something bothers me. It has ironically fixed more fights than pretending to be nice, and being passive aggressive instead.
Another book I recommend is passionate marriage by schnarch. It does focus mostly on sex but does a good job explaining why many WAS and WAW get MLC.
