I wonder what are his explosions about? Is it always about money? Him wanting you to spend on him and you not budging or him taking it without permission and you daring to question it? Those were some examples, all money related.

Or is it sometimes something else? What things are pushing him over the edge?

So I’d say whatever that is needs to be worked on, but now, not when he explodes next time. Maybe instead of addressing his explosions, you need to address what causes those explosions
