The amplitude of his objection is what worries me.

Don't allow him to be rude or disrespect you. If he screams, calmly say "I'm sorry you feel that way, but I won't be talked to like that. Come back and talk to me when you've calmed down," and then walk away.

"I want to make amends" are words. WORDS ARE CHEAP. It is his ACTIONS that you need right now, and if he can't understand that, then it tells me that he isn't sincere.
