Very nice e-mail, I think. Very kind and generous. And don't discount your flattery just because he seemed not to acknowledge it. I know my H can't get enough of that kind of praise, which is probably why he goes seeking it out with new conquests. You can lay it on as thick as you want.
You certainly gave him a full and generous apology, and that's important for you as well as for him. Yes, he does sound pretty macho, but that can work in your favor, if he feels protective of you and the girls.
