Ok, I keep getting mixed up with how he says wife when they haven’t had the wedding yet,...

I think they're already considered married, and the wedding is just a formality. They may even already be married on paper

Technically they eloped, so most likely it's just for formalities. And Allen promised her a grand wedding, so most likely they're waiting for the official ceremony just to show how strong their relationship is

Oh ok now it’s coming back to me it’s been so long thanks
