To change the arrangement I have with EX regarding DC's.

[Runner234]

EX currently sleeps our 2 DC twice a month. Every time the DC go I have to pack for both of them (Ex also requested that I pack a bag for each as packing it all in one bag wasn't good enough) then he puts all the dirty clothes in a bag and gives me this when he drops them back home and I have to unpack and wash their clothes from the weekend and repeat this every time.

EX pays good maintenance but I am starting to think that this is an unfair arrangement, if they get really muddy I'm the one who cleans it up, he once left their shoes caked in mud and I spent an evening cleaning them.

So WIBU to buy a load of clothes (ex will expect me to pay out of my maintenance) give them to him and say that they're for your house so I'm not spending my time packing, washing and unpacking when all he does is pick them up and drop back dirty washing?

AIBU to moan about this and would you buy him clothes for his house or let it go?

No, I don't think that's unreasonable. He has got a washing machine and knows how to use it, I suppose? It's like he's expecting you to do some of his parenting for him when it's his time. The maintenance will have been worked out for the time they spend with you btw so isn't a factor here.

would you buy him clothes for his house or let it go?

Neither. I would expect him to have clothes at one of their houses (his) for when they came. I've heard of Wifework but this is exWifework.

Does he pay a lot more than CSA?

Stop doing it, he’s taking the piss! The man is a grown adult and can wash his children’s clothing. If you wish to be kind tell him to keep the clothing you have put in their bags at his house for future use.

He doesn't pay more than CSA he used their calculator to work out how much maintenance he was expected to pay.

Then he doesn't pay 'good' maintenance but 'minimum' maintenance.

In which case he can buy clothes for his home.

You're being more than generous giving him clothes to keep for his house.
