I Don't Want the Obsession of a Twisted Archduke

I reincarnated as the wife of a cursed archduke in my own twisted novel. As the author, I took responsibility and set things right by lifting the curse, which was the key to returning home. I thought my job was done, and just when I was finally trying to go back, the archduke asked me, "Did you really think I wouldn't know that you’re planning on returning to your fiance?" He had completely misunderstood! "Whether you like it or not, I'm still your husband. I'm never letting you go back to that bastard." All I want is for him to please let me go home!
