I feel for ypour wife, In a couple, the one with the best cleaning standards always suffer.
Just like you, I am cleaning deep every 2 weeks, however i like to keep the house tidy.
And my wife is incredibly messy, nothing is ever put in its place, wraping are left in the sink instead of the trash, there is constantly some cisors out with food on it, clothes on the floor in every rooms, and so on.

She feels like we need a cleaning lady, no we just need to keep things tidy up every day.
To her its an insurmontable challenge, like i am talking about doing an marathon.

Well, i just end up cleaning up, a lot, every day.

Is it really a big issue that he use your fridge?

I thought you would be worry about some cash you left in some drawers

its ok you can improve everything :

I dont know about you, but as far as i can remember eating/drinking out was seen as luxury.
My parents used to cook and pack all their work lunch meals.
As family day out, we would eat sandwiches prepared back home.

Just this saves a ton of money, and also soda is bad for health.
Switch it for some flavored water you can prepare at home. Lemon water, mint water, orange water. Or even some sugary powder if you really crave it.
