How can I set a boundary in a feminine way, after the fact?

Long story short I feel like I'm giving way too much and now my BF is used to "wife duties", and I do not know how to express I find it selfish. As I left his place Xmas day to head home and prep his gifts, he gave me 2 bags of his dirty laundry. I was sort of in shock when he did this, and just calmly took them and said nothing. But TBH I feel like I'm being taken advantage of, and I don't know how to express that he needs to step up his efforts if he wants me to do these types of things for him (noting that currently has the use of it one arm due to injury).

Is there a way to say this after the fact? It seems petty to give him back his dirty laundry, but I'll feel like a doormat if I do it and say nothing.

Sorry but I just am really struggling with how to set boundaries, and still feel hurt from my xmas experience with him. I'm trying to think positive and see where he is "giving", but from my view he is taking far more and I feel I'm being taken for granted. Ty for input. PS Surrendered Single should be arriving today so I hope this will help too.
