My house was a wreck - for the length of the marriage, her turf was cleaning, I had other duties within and outside the house structure that evened the workload out.
Since before she filed, the house had not been cleaned. I am not a clean freak, and really am not good with cleaning clutter. But I had had it, as we were about a week away from the Hoarders crew showing up. On a weekend when STBX was out, I invited some family members who knew what was going on over to the house. I took some massive hits to pride (and still getting pinged to this day), but for a day straight they de-cluttered while I ran the stuff out to the garbage/garage, then focused on the detail cleaning. At least the clutter/crap was not mine. Her room was a mess after we offloaded all of her stuff into it.
It is not totally clean, but it is livable now, and I can continue to cook, etc. Now that I had help with decluttering, I work on the cleaning, and make sure it doesn't get cluttered. She might help once in a while, but I never ask her to. I still do the other things inside and outside the house. She has less to do.
I also have found the time to spend more time (if that was even possible) with the kids. Pick them up from school, schedule Dr appts, stay home with them when they are sick. I don't rely on her for much, if anything. That's how I stay cool.
Don't worry about your perception of how lazy she is get to you. If it is bothering you, do something about it - and I mean the environment, not the person.
