I hurt his feelings

My hubby tells me I have hurt his feelings terribly. I know thats not possible. But he doesnt. How can I handle this? I have all ready told him I was wrong for acting the way I did and that I am sorry. That doesnt seem to be enough for him. He cant seem to verbalize what he needs. He is sad and cold toward me. Other than just wait it out do you have any suggestions? He seems to want more.
