Hi
For the first time ever you are maintaining boundaries and insisting on time apart. It may be that he is over spilling into other parts of his life as he no longer has you to focus his moods/rages on. Although it is probably embarrassing for you as a couple, it will mean other people get to see his behaviours snd reinforce to him that he needs help.
Take care

Thank you. This makes sense. My worry wasn't so much embarrassment but if he is truly losing it, I worried I would get even worse behavior. I hadn't thought of the idea that he just doesn't have me as his "target" or outlet for dysregulation. Wow.
