That's the critical part right there. However, there's an "and" to be considered. Their feelings were valid, and so were yours.

From what you wrote earlier in the piece, it's clear they had a lot of expectations as to what you "owed" them (e.g., doing laundry). We get upset when our expectations aren't met, whether or not those expectations were reasonable.

A true sign of emerging adulthood on their part would be to acknowledge that your feelings were every bit as valid as theirs. Then, everyone can move forward.
