I have similar situation, our relationship was very fast i believe it is true and honest. My family relatives and friends neighbor was their on out wedding day, though my husband parents wasn't there his close friend was present on that day.
For the proof, we only have 45 emails, 1st vist, 2nd visit with husband friend, wedding reception and honey moon pictures. And also i took 4 screen shoot from computer, and screen shoot our skype call. Receipts 1st visit ( white water rafting,cinema ticket, hotel receipt and engagement ring) that's the receipt we have, all of our the receipts was lost because we didn't know that it was need for proof, 2nd visit he stayed in our house, we have few receipts (venue and the food, the entourage clothes that we rent). we submit all originals receipts plus the itineraries. We also answer every application
