It sounds to me (having been there myself over other issues) that your husband realized he'd messed up big time but didn't know how to SAY he was sorry. So, he's doing about everything he can think of to SHOW you that he is. Is this typical behavior for him? If it is, you may be better off accepting this apology for what it is. Not everyone knows how to express themselves verbally -- especially when they're in "deep kimchi." You're the one who knows your husband (although I don't mean to say you can read his mind).
If on the other hand this is what he does to AVOID apologizing in any form, he probably needs to be called on it. It all comes back to the intent behind it, and only you can judge. Good luck!
HERE is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head, behind Christopher Robin...sometimes he feels that there really is another way [of coming downstairs], if only he could stop bumping for a moment and think of it.
