Lazy partner can’t cope

Weekdays it’s just me & my two little girls at home (1&3 year olds) and my partner comes home Fridays, heads back to work on Sundays. Now through the weeks my house is spotless, we have a routine, everything’s good, all jobs get done. But whenever my partner is home it all goes out the window, he is so untidy, he doesn’t clean up after himself & he never knows how to put things back.. he is now home for good and working InTown, today is the first day his staying home and I can’t handle it, not for every single day anyway 😩😩🤨
