I live in a jagmag karta ghar. I am married and both of us are working fulltime.
The place alhumdulillah is a decent size but we maintain it.
key is organization and routine.. i dont know your situation so will just give some general advise based on some observations.
One of the biggest thing is organization, everything needs to have a proper place, everything needs to be in its proper place. one of the problems i see especially with desis is that they are packrats..way too much stuff and not enough or proper storage for it, crammed closets, spillign drawers, bursting at the seams kitchen cabinets.
the first thing to do may be to get rid of everything you dont use and is just there because "it may be helpful sometime" then..things that you dont use ona daily basis, put them away, find a place where they can just be stored and accessed when needed but that they are not in your way or competing for space with items which you use on a daily basis.
set a routine and make sure people follow it. i.e. laundry goes directly in hamper..laundry gets done every X days. have waste baskets in every room, the trash must go in the waste basket and then collected in a big bag every X days.
keep cleaning supplies and instruments easily accessible. if someone drops something, its easy to just grab a hand held vaccum cleaner and clean it right up, rather than feeling overwhelmed that you will have to go drag the large vaccum cleaner from the broom closet from behind clothes and shoes and junk. (being organized makes sure that everything is easily accessible when you need it)
wash dishes right away or put them in the dishwasher right away after you are done cookign/eating.
its when things dont get taken care fo right then and start accumulating then it can become overwhelming.
cookign wise, i know what my mum used to do she will prepare a bunch of meat and put is in the freezer in smaller packets, as needed she will take the meat out and make allo gosht, timatar gosht, palak gosht etc. maybe you can try some of that. I dont know what your husband's expectation is i.e. does he expect a freshly made 8 course meal everyday or not, so i dont know.
the process of getting organized can be painful..takesa a lot of time to go through the junk, but once that is done, its a very smooth sailing.
Do it over a weekend, enlist yer husband's help. make it an event..get food delivered, get movies/cartoons of kids so theya re occupied and tackle one room ata time. get the kitchen sorted, and then hit bathrooms, closets etc.. u can figure out a workplan here :)
and then...when all is clean..go take a vacation, and make it a real vacation..no chores, no cleaning. then you will return relaxed and to a clean organized place which will take a fraction of the effort to maintain than it did to constantly clean.
