No, he's not sorry. Your DDay was only about six months ago. At this point, he should be devoting 100% of his energy to helping you heal. Part of healing is talking about it.
He doesn't want to look in the mirror to see himself and what he's done. He wants to put the burden on you so that you can just sweep it all under the rug and suffer in silence.
Yes, you are worth way more than that. Don't let him step over your line in that sand. If he refuses to do the work to heal the pain that he caused, he can go inflict pain on someone else.
