You say she doesn't get it....well probably not but they are at least watching your actions. On top of that, should not matter...you cannot control what she gets, only how you act and react.
I also felt like I could not figure out what I didn't do right in the marriage.
Someone has to be blamed....going to be you!!!
Seriously, my wife said all kinds of mean, horrible things that she later could not even remember saying and for the things she did remember - felt horrible for saying them.

Made it through the WAW, living happily together now. And I am much wiser for it!
