I understand you want to know what it means but honestly, don't waste the energy trying to figure it out. I am not being unkind I am simply saying you won't know so why bother thinking about it?
I think it is best to give your H the shortest, most neutral answers possible. He sounds very angry and nothing good will come out of engaging in conflict with him.
Sure he is annoyed! LOL! You are not picking up his every call and waiting around for him. He is losing control of the situation and he doesn't like that. Too bad.
Keep being fabulous, happy, confident and let him behave how he wants.
