Hi Denne,
Did you send along receipts of items purchased? How much your wedding cost, who paid for what? Description of the day? How many people attended? What gifts you were given? I would send those things, with more pictures. Also some testimonials from people who attended, like letters. For relationship, get testimonials, pictures, copies of love notes, emails, phone logs, text messages, Facebook statuses/messages, shared property, accounts, etc.
Please members of the house, if you have more advice, please weigh in. Let's give Denne lots of ideas.
