Your H was grumpy because he didn't get much sleep last night, because he didn't know where you were. (Plus maybe having to actually deal with three little ones without you or his Mommy there to help out.) The fact that you were not there when he got there made him think that you were gone all night.
He got very angry not because you made him 15 minutes late, but because you made him realize how much he still cares about you. Even if in his front brain you are the past, or a backup plan, in his subconscious you are still his wife.
