We submitted her phone bill which states how often i called her and how often she called me. we have an average of 8000 texts per month, so we picked one day for each month of the last year and printed off how often we texted and how many phone calls we had. weve submitted a screenshot of skype calls between us in the last year.
We've submitted 4 letters i wrote to her, and 3 letter she wrote to me. We also added a bank statement that shows that we've made a joint bank account even a year BEFORE we got married, the booking confirmation for my flight to canada last time i visited her, and eventually a copy of each others will, which is beneficial towards the other."
