Yes they will if they carry out the series that far I mean Elena in the movie looks like she would want to finish high school first! BUT YES i think they will get married! jeesh LUCKY ELENA!!!!
In the book, they do right about the time Katehrina comes around. So, possibly, if they stick to the book. Hence why Katherine will want to kill Elena and stefan lebih than Damon, but still damon...if sticks to book
