US Immigration from Ecuador

Hey!

So my fiance and I originally met in 2010. I went to Ecuador in 2010, 2011 and 2012. We have spoken on fb messenger and whatsapp every year since then. I am back here now because of the 2 year rule. In gathering evidence, is it important to show our conversations throughout the last 7 or so years and if so, how do you all think is best. All of our conversations are in spanish and I have gone through them all and screenshotted the ones where we speak about marriage and love and our future together...it is ALOT, so do I just print out all those screenshots? We also have my boarding passes, airbnb stay, and photos of me with members of his family. I have also had conversations with his mother on fb messenger. I guess my question is are conversations necessary to include? How did you all print yours out? What about photos that we exchanged to eachother?

Thanks
