Dm would not let me die
So i am i a campaign and we were having a great time. After the session i told the dm that i want my character to die at the end and if he can make something for it, she gets pouty and says that she doesn't want any character to die and wants a happy ending, i say u can still make a happy ending, even with a dead character and i want my character's arc to end in death and explained why it would complete his story. My dm was not having it and ignored me. Am i the asshole? did i do something wrong? What should i do instead?
