It's not selfish to want to be compensated fairly for something you have created.  I don't want you to get screwed again, but there is some part of me that has to believe that you want to tell the rest of the story and also that you could find a way to set things up, so at the very least you would be compensated fairly for your efforts.  

As a fan, as someone who has fallen in love with the story you have woven, I sincerely want to know how it finishes.  Or maybe I don't. Maybe it's better this way.  I don't know.  All I do know, is that if one day you do decide to tell the end of the story, I would do whatever it takes to make sure I'm within earshot when you're telling the tale.
