eight years!!! wow!!! thats quite sometime.
first off.
have you tried makin arrangements with her?
maybe certain days of the week you can pick up the children and she can do the dishes those days.
that way it kind of switches up the roles.
or honestly yall can do this exercise...
when my sister and brother-in-law were havin issues the therapist told them to make a list of things that they felt were creating problems in the house...
and everynight you talk about one problem...
and you come up with a solution together...
and truthfully it wouldnt hurt to compromise.
meet in the middle.
like make the saturdays or whatever day she has off the day yall clean the house together.
that way you wont have to clean nearly as much.
and when the kids bring out toys or books, when they are through playin ask them to pickup their toys that way the kids.
that should help too.
