W has practically stopped helping out around the house. We were always lucky. It truly was a 50-50 split with chores our entire marriage. Cooking, laundry, cleaning, getting kids ready for bed, etc. W does very little now. Initially I picked up the slack but recently I have let things slide and you can tell. She just doesn't seem to care. Oh well. Just more of how she has changed.
My W did the same thing before S. I think it's their way of reinforcing to us that they're leaving. The one difference is I did pick up the slack. I took everything over. I did it for me, not her. I wanted to make sure I could handle everything before she was gone, and also so I could get feedback/ input from her if I needed it (like all those darned washer/ dryer settings, my W/D look like space shuttles).
