It's hard (and maybe unfair) to pass judgement without knowing what really went on and without hearing both sides of the story, I think. What happened? It sounds like a scene went way too far and that he's blaming you for not speaking up....but that is just reading between the lines on my part, really.

In general, though...I'd expect some form of explanation or care, too, without blaming or accusing anyone, just showing care and concern and then finding ways to make it better the next time. But if the relationship is worth anything you should be able to communicate that to him, right?
