Is is a single incident OR is it a beginning of a trend if he thinks he can get away with it?

You need to be firm that this is NOT ok behavior in a marriage & it will NOT be tolerated.

Yes, it would be good to find out WHY he thinks he can but it sounds from what you say that he is trying to lay the guilt on you & who knows if talking to him will change his point of view.

If you do have a REAL discussion about this.....don't alliw him to make you feel like a doormat which from what you write it makes him sound like he is doing.

It makes me wonder if your marriage has really been as good as YOU THINK it has been because stuff like this doesn't usually come out of the blue. This feeling probably was building up for some time inside your H before he finally exploded because that is how people work. It is NEVER just a sudden thing.

Yes, counseling might help BUT you may have to force the issue if he really thinks he is right.
