Oh no that sounds scary ... I wonder why they don't really like Facebook .. I understand people fake it but for a long distance couple it's a great tool for communication/pictures/etc .
So how stricked are they for Facebook ?
In what way? If Facebook is all you have, then send it. They will consider it as part of your relationship evidence.
It's really just a suggestion that if you can show enough regular communication without including Facebook, that's preferable because other types of communication may hold more weight, but they aren't going to refuse the visa if you include stuff from Facebook... unless they have reason to believe the relationship isn't genuine.
I've been taking screen shots and such but yes it's taking forever to get back to 2015 to be honest I don't have much from 2015 other then some flights we have taken to see each other and a picture of us at the rugby World Cup where we are infront of a sign that says 2015 rugby World Cup England .. we have the tickets of the match we met at in October .. I'm just trying to think what else we can do ... I have posted pictures on Facebook with the dates of people commenting as well with the dates next to it .. but I'm kinda at a loss here .. but 2016/2017 we are well stocked with information
It's only that 2015 from Oct to Dec any tips ?
I'd either try to access it using the Chrome Addon suggestion above, or just make a note in a cover letter that you are unable to retrieve the messages from Oct-Dec 2015.
It's only a 2-3 month period from 2 years ago, so as long as the rest of your evidence is strong and covers the 2 years since, you should be fine.
What they need to make sure is that it's not either a forced marriage or a convenience marriage to qualify for a visa... if you had only met once and hadn't had any communication at all in the last 2 years, it would look suspicious, but as long as you can show you have been communicating and visiting each other, you'll be good.
