Partner doesnt feel appreciated

My (30f) husband (30m) has stated that he doesn't feel appreciated in our marriage, and that he feels like we're roommates more than partners. I'm neuronontypical and really struggle to understand social advice that isnt "if he states that oh, he needs to do the dishes, you could do the dishes for him first". He's not materialistic, and is incredibly self-sufficient, and i don't know what to do. Googling hasnt been very helpful because the advice is broad and vague. What does your partner do that makes you feel appreciated and seen and valued?
