You are really afraid of this man's anger. You are trying so hard to care for him because you don't want him to become angry.

Your worry for him comes from the fear that he would become angry at you if you were to discontinue these caregiving behaviors.

Yet you are doing all this caregiving and he's angry at you anyway. His anger is not about you. He is just an angry person. Whether you help or don't help, he will still be an angry person. He is not angry at you, he's angry at life, and you're allowing him to take that out on you because you can't stand his anger. You are personalizing his anger when his anger is not about you. Because you personally are afraid of anger.
