Part of the communication is checking that both of you know what one another's needs are, and also that both of you are aware what the other person is already doing.
For example, he might tell you that he's already accommodating you because he doesn't do x, or sometimes does y.
You might still say that's not enough, or doesn't actually help you, and that he needs to do more, but then you at least know that from his point of view, he's doing something for you. And you can acknowledge that, and say "but what I actually need is z"
Otherwise both of you get frustrated with one another, "I do so much and they don't even acknowledge it!"
