I've name changed in case she's on here.
DSS is 15. He stays here from Friday afternoon until Monday before school EOW and more in the holidays. I usually wash uniform on the Friday so it's dry (although he does have shirts and trousers here so it wouldn't be a problem if it wasn't).
I then wash his clothes he's worn over the weekend on the Monday/tuesday and I put them away for him. If he's here in the holiday, he goes home in clean clothes and j still wash the clothes he's worn over the weekend.
His mum messaged and said that we shouldn't be ‘keeping’ his clothes as she has payed for them (although some clothes DP has payed for are at hers). When he's off school he wears whatever to go back home and it doesn't matter if we've payed for them.
Are we BU?
