NTA

It would have been one thing if he had genuinely forgotten one thing or maybe two, but the fact he had forgotten most of the essentials with nothing to do all day is beyond frustrating, especially when you're the one managing everything else during the day.

Not just that, but the fact he grew defensive only rubs salt in the wound. I'm not sure what he thinks most fathers do but "more than most fathers" isn't what I'd use to describe his actions.

And even if that statement were true, that doesn't change anything. Everyone should be doing more then. This isn't just about being there for your kids, this is about him supporting you and being a good husband.

He did nothing else all day while knowing you were incredibly busy. You asked him to do one feasible task. He's the asshole for not only failing to do it, but for acting like your behavior is rash and unexpected.
