Apologize and if necessary seek marriage counseling and anger management for yourself.
I hit my husband what should I do now? Context: I was having a melt down and hitting myself and my husband tried to stop me. Even though I knew he was in the way I carried on and I hit him once.
He's probably just fine with what happened---he was obviously trying to help.
Bring it up with him.
Well, I am sure your husband knows it was an accident, and a simple apology should suffice. But if you really want to make it up to him, tell him you are ready to seek counseling. Hitting yourself is not ok either. You need to get some help to learn some coping skills so you don't meltdown like that.
