NO MEASURE OF TIME WITH YOU WILL BE LONG ENOUGH, BUT LET'S START WITH FOREVER

DETAILS: From Pinterest
This quote appears in Breaking Dawn Part 1 when Edward is speaking about Bella at the wedding reception. It is also in the Trailer. Edward says "No measure of time with you will be long enough, but we'll start with forever" 
Note: There are a couple of variations of this quote around, that is because Edward says it a little bit different in the trailer and the movie.
