The way things stand at home....both sides see us as the enemy. To my side, Maven is the enemy, to his side, I'm an enemy, a traitor to the crown, and a murderer of the royal family. Nobody would support us, and I doubt very much the three from home would support us, despite me assuring two of them I'm happy. I'm pretty sure the third wants to murder me. Slowly.
Besides, it makes no sense to have a big wedding here.
You're a Mikaelson, right? I can imagine any wedding your family have here would be lavish and huge.
