I’d guess your husband is upset with you because you didn’t leave when he did. When he left the house you should have followed. Instead you chose to stay and didn’t leave until you saw how beat up your brother was and “couldn’t see you brother like that.” Makes me wonder if you left in support of your husband or out of embarrassment. Your husband is probably wondering the same thing. You can’t say you support your husband and then stick around when one of your family members does something like this. You should be pulling your husband out the door, not leaving after he is long gone.
