I don't know, given how they interact with each other, I think they might be able to last.
I mean I can just picture a typical morning....
Emily cooking breakfast
Brad comes in: "Good God, Em, that smells amazing."
Emily: "Oh your so sweet!"
Brad: "After breakfast, I have a little treat. I'm taking you and little Ricki on a picinic!"
Emily: "Shut up!"
and just because no conversation is complete without it,
Brad: "I always wanted to do this so badly."

THANK YOU, THANK YOU FOR THAT SERIOUSLY AWESOME DIALOGUE.
That just explains so well why so many of us wanted the story to be BRANTAL... Emily + Brad is a snoozefest!
Say what you will, but I was never sure about the North/South thing.
Chantal, from Seattle, was going to be Very Southern Brad's Bride?? Hmmm... always gave me pause.
