Bad Endings

I just scanned through Rosemary and Juliet and found yet another sad ending to what could have been a good young adult lesbian romance.  I'm sure that it was based on the way too many young relationships like these end up. I had read a comment that one author who writes young adult lesbian stories said about publishers not wanting the story to end happily because of the general public view of the story but I refuse to change the ending of the story I've written from a happy ending to a semi happy one to make a publisher happy.  I will self-publish it myself first.
