First, thank you for remixing my name. I always wanted a second "n".
The best way to express it is to do just that. Let him know what you observe but be willing to listen to what he has to say in response. And also make him listen to you as well. This is just a communication issue that needs to be addressed. It's also not very uncommon.
I don't think that you're expecting too much. I think that both men and women fall victim to this phenomenon.
And since he's likely to tell you that you he has no clue what you're talking about, you should give him examples and also let him know how he could better make you feel appreciated. You think this should be common sense but men respond much better to direction than what we're "supposed" to know. Just like women.
