A person who loves you, a person you care about, always has the ability to make you angry.  If the reaction you have to something a person does is apathy, it is far more serious.  A marriage (or any other relationship) almost never makes it back from that.  It is usually finished at that point so if someone has the ability to make you angry it is a good thing:  it means you care about the person and the relationship is still alive and has hope.  Anger is always an indicator.  There is not something necessarily wrong with it so learn from it.
