I think basing things on the actions you see is a healthy thing to do. I always say it's actions, not words. It's quite likely that he has not figured it all out for himself.
I hope you have a face to face support system in place such as Alanon, Celebrate Recovery, therapy, whatever. That's important for you. And keep coming back here to SR. This is a place of great support from people who really do understand.
It sounds like you are keeping to your side of the street and letting him figure out his recovery, and even if you don't always see it, that's a really good thing.
Gentle hugs.
