You have 2 major issues here!
1 strategic incompetence!
He’s deliberately refusing to make the effort to do the task right in hopes you’ll eventually just “give up” and say “don’t bother it’s easier if I do it myself” then he’s off the hook!
2 finances - why are YOU buying the dcs clothes?! Personally I think as a family the money should be pooled anyway, but even if it suits you to have separate finances they’re his kids too! He should be covering at least half of clothing costs and when he’s wrecked them he pays! Bet he’d be more bloody careful then!! Let me guess you cover all dcs costs?! If so you have MUCH bigger problems than laundry!
The suggestions to write him notes etc just require more effort from op and allow the husband to play the child role still. He’s a grown ass adult with a job, he’s perfectly capable of handling a load of laundry CORRECTLY!
I’d actually be tempted to “accidentally” ruin some of HIS favoured items of clothing!
Just tell him to stop helping if he cant be bothered to do it properly as hed wasting money, time and making more work exactly what he wants to happen!
Seriously, how do women tolerate these lunkheads? I too really DON’T understand this!
My ex had his moments when we were first married, which I knew he was at it as prior to marriage he was perfectly capable at doing chores! Better than me at some (he was army so excellent at pressing and shoe shining!)
One almighty row not only from me but his parents too (this was NOT how he was raised, his parents have a very equal marriage and all 4 dc boys and girl did their share and chores weren’t assigned on gender lines and were often rotated) and he knew better!
Like hell would I have put up with this shit!
At the very very least IF you relieve him of laundry duties he needs to be responsible for another equally onerous task - maybe bathroom cleaning?!
It might be the supposedly sensible mature thing to do “discussing calmly” but it’s not getting you results! I’d lose my shit with a man who did this! If it inconveniences/causes his hassle to not do this task properly - he’ll do it properly!
