I can understand his need to be left alone after such an emotional experience. I need that myself. It literally took my husband decades to accept this trait in myself. Sometimes he'll still press me if it is something that involves him. I do not know about your husband, but I have a sharp tongue and if you do not give me enough time to gather myself I am going to say something I regret. Sometimes we need space.
I do hope that the two of you come to some sort of understanding on this. The evil ones seem to outlive us all
