Yep, this is very common, no matter how well the recovery is going and no matter how much he loves you.
Keep this in mind, though, for when he comes home and you find other things he does doesn't meet your expectations, either. In fact, I'd work on keeping your expectations as low as possible. Not to say he won't recover successfully. But early sobriety (even GREAT early sobriety) is full of ups and downs for both parties. I've been on both sides and I know.
My first husband (now sober almost 35 years and still a great guy with whom I'm very good friends) drove me crazy with some of the things he did/said the first year or so. (And probably vice-versa--I probably drove him a little nuts from time to time.) It takes a while before the sober alcoholic becomes "normal"-ish.
Glad you had a nice holiday.
