Fine to vent G. And getting your W to drop the resentment may never happen , that's her choice
Doing things more around the house may have made a difference or may doing them wrong ( in your W eyes) may have made things worse Who knows and it's not worth worrying about now
IMHO , things can't change with W while things remain he same , the more you GAL and start to to enjoy your life maybe , and it's just maybe W will appreciate you for what you did and opposed to what you didn't do
Keep being the best dad you can and build a life for you as if W is gone because worse case your preparing for the future and lest case your becoming the best G you can be
