I'm going to refold all of the laundry that my partner folded for me.
Why are you going to refold all of the laundry they folded for you?
I don't like the way the clothes were folded and I don't want them to get wrinkled.
It's good for your partner to do that for you. You should be grateful for them folding your clothes. That was nice.
I just wish they had folded the clothes properly so I don't have to do it.
I'm sure your partner thought they were helping you by folding the clothes. If you're not happy with the way the clothes were folded, you should show them how you like them folded. Be considerate of their feelings when you talk to them though.
