Have your emotions leveled off a bit? You expressed how angry you were after the argument and how things have gone back to a little bit more normal. A return to work with some accommodations is positive forward progress too.

I think your point of view and concern about how your husband reacts and treats you in difficult times is very valid. From an outside perspective and not seeing the whole picture, I would hope you made an individual appointment to discuss your feelings. Life isn't always smooth and easy like it was in your 10 month reunited honeymoon phase. How people navigate the rough times is far more important than how the roll along with the easy times. If your husband insists on ignoring the rough times, you are 100% correct that he is a fair weather spouse.
