Emotional roller coaster!

I cannot stop thinking about sad things after another fight with D. He would not care if I leave this world after all we would not go to the same place anyway. I can't sense it when I am affected by the bad emotion, instead, what he says and how he reacts just make the whole thing worse. He just cannot or do not want to get it. He is not willing to share his feelings which he claims that he does not have. I asked him to recall a few happy memories in childhood, after just one try which was his 15th birthday, he shut down completely not even mentioning the question of a few unhappy memories. He turned around and said that he did not have those memories, and that account just made me feel that he got impatient with why I asked the question. I went to explain why I asked the questions and further described some details from the documentary I just watched. He went all resentful and confirmed that he did not remember or think about happy or unhappy memories. To me, the way of thinking is just not humane. Unless, he deliberately shut down the memory or was too impatient to bother to say anything. Either way makes me feel insulted. " how stupid you just asked that question?" kept running in my head. To me these questions and the answers with the interpretations are quite relevant to what happened to me. That's how every time the old sad memories affect me with my emotional roller coaster. Early emotional memories do affect one's life satisfaction of later adulthood. I lost my grasp, felt angry, even raged, and threw things on the floor. I did remember clearly how he had recalled to me that his mum threw something at him and broke his forehead (and he made sure that I heard him saying "I don't want my kid to have that"); how he enjoyed trips with his farther along. I got even more angry because it was obvious to me that he either didn't care about what I said or would not like to share his feeling with me at all. He confirmed that he did not think that way. Of course not, otherwise why would it be a question. I don't understand why he is so denial and defensive if he does not have anything to hide. Even so, he is busy right now (so do I), can't he just say "maybe we should discuss this question some other time, it will take a long time." Why does he have to be so brutal and hostile about my question and invitation to discussion? I don't understand whether I have issues or he indeed does. I don't understand why it makes me feel that his emotional life is so much more superior than mine that he would not want to share and bother to care about mine.
