How far is domestic abuse?

My husband got into a fight. It ended with a plate being thrown above my head. I was done trying. Before I would have screamed or shouted or say something rude back. This time I just said ok, he grabbed my dinner plate and throw it. I want to go forgive him. I’ve never seen him cry in 3 years. And I want to say it’s ok and I know he didn’t mean to. He’s punched door and walls. Never leaving a mark. Now there is a 12 inch hole in the wall from the plate. I am not innocent I’ve said very mean things. Done very mean things. Not this time. I was done trying, I did not raise my voice or said anything mean. But I feel like this is too far? How far does it have to get to be called abusive?I’ve locked myself in our room and not said anything. I said We’ll talk in the morning. I don’t know what to do.
