Self centered vs. Self absorbed

Recently I’ve dealt with someone who seems to draw out my negative emotions and reactions. I shouldn’t say negative. I don’t think emotions can be negative, I think how we handle them can be. Anyways, this person has accused me of being self centered by saying, “you know not everything revolves around you.” Interestingly enough, they say it during times in which I am unbothered by their life. I have also learned that this type of behavior is common when you are ACTUALLY self centered. Because of this I have found myself doing unnecessary research into myself. I’ve come to realize this person is simply upset because they are not the center of my focus.
