What do you do to alleviate your partner? Does it put a strain on your relationship?

I know this is one thing we struggle with a bit. My husband does a LOT around the house and a lot of times seems like way more than I do. Part of me feels really bad about this. I don't want him to feel like I'm slacking or not pulling my weight. On the other hand, part of me feels like he doesn't prioritize and some things that could be left until later, he does anyway and creates more stress for himself. On the other, other hand, maybe I just need to try to accomplish more even though I'm not quite as productive as him (and I'm normally ok with that )

This is something we are actively working on because it does put a bit of a strain on our relationship.
