traceypharm, I found a copy of LJ Smith's emai here
link "You see, I’ve been fired from The Vampire Diaries—mainly because instead of giving my publishers the strict Stelana they demanded, I went ahead and
wrote what my hart-, hart told me to do. They wanted Elena to “realize that she was fond of of physically attracted to Damon, but that her one true love was Stefan.” But I didn’t see the series that way. And so Midnight is the last
Vampire Diaries book you’ll see door L. J. Smith."
She goes on to say: "Even though they are copyrighted to me, I still can’t write
them without Alloy’s permission. And they really hated any Delena content—as well as the many scenes I had gegeven to Bonnie, which they wanted to cut. They demanded only Stelena... u can kiss any meer truly meaningful Delena moments goodbye, because I’m afraid it just isn’t the view of Harper of Alloy."
She ends the emai door saying that she's sorry that Delena readers will have no hope of anything other than a Stelena endgame.
