I agree with GEL that he may never read the book. My H read the first chapter, and I never pushed him to read more. I read some passages of PM to him, but it was clear that he wasn't getting into it, so I let it go.
Talking to him about things that are important to you, though, that is a whole different ball of wax. I do think you can initiate discussions and ask that he follow through. You can do it in a way that he knows his actions are appreciated, you are not criticizing him, but you want to take it to the next level.
It sounds like he is making a very big effort, so let him know that you appreciate it, whether or not you end up talking about your gripes.
