I expect my stay-at-home husband to have our house looking immaculate when I get home
Are you expecting him to stay on top of the housework no matter how tired or busy he is?
Totally. I pay our bills and some of his and he is mostly home with the kids while I go to work. It doesn't matter how hard this job is it's what he chose to do.
It's great to have your husband be able to stay home and raise the kids. You shouldn't expect him to always have the house immaculate though. Think about what he might have had to do that day to keep him from cleaning the house.
But I am really busy and I can't do these things myself.
I understand there is a relationship dynamic here, but I think it's a good idea to let your husband have a breather sometimes too! He works just as hard as you do, and it's not fair to think he has to do everything.
