I don't think you need bother to send call history or text messages... It's really a personal preference. As long as you send some sort off proof you have been keeping in touch.
Myself and Harlene printed a couple of pages off our facebook messenger chats (leaving out the +18 content) Also a couple of pages of our skype conversations.... Also we included birthday/valentines/Christmas cards we had sent eachother (Harlene kept the envelopes with the postmarks on them, I didn't think of that!
I know how anxious I was to include everything but the kitchen sink.... But really it is not necessary to go overboard.
Good luck with everything... Saw the pictures on your facebook of the wedding. Looks like a great day was had by all.
