So I have this idea, but I'm not entirely sure how I want to go about writing it. I'm using a controlling relationship to illustrate concepts of non-attachment, or "learning to let go." The main character is abusive (not physically), and his abusive behavior is driven by the anxiety of losing his girlfriend. While his girlfriend has her share of flaws, the story is predominantly about him and what he learns from the relationship. I think that writing from first person POV would make his personality, motives, and development more clear. I want the protagonist to be relatable enough so that a reasonable person could understand his perspective and maybe even envision reacting the way the protagonist does. However, I'm not sure the reader would want to be put in the shoes of an abuser. Could I make him a relatable character despite him being abusive? Would it be easier to use third person POV?
