My H went by the book DB even after I moved out...and I definitely noticed. And it definitely made a difference. We still had to see each other to deal with children, school functions and the like, and he was his absolute best each and every time. I completely understood, though, that he was his best for his own sake, not strictly for me. There was/is still a spirit to what he was doing and I sensed it...and liked it very much.
Cheers ~~~
