When Elena was human, she chooses Stefan as the vampire she wants to be with, Yeah!!!! And now that she is a vampire, I’m pretty sure that she is going to choose Damon, Double Yeah!!!! But I’m not sure if we will see the happy ever after that Delena Фаны или even Stelena Фаны (if she stays with Stefan) want to see at the end of the show. Because, rumors say that, the Salvatore bros will try everything to make her become human again. So if they succeeded than they are going to see Elena and one of the brothers have a happy ever not after, but a “happy ever till she found a human with whom she is going to get married and have Дети with blue eyes." Because we all know that even if a Delena или Stelena baby will be great, Вампиры cannot procreate.
So I think that whoever she wants to be with now или after Далее season, it is not going to last. So no happy end for the bros
