You should make the initiative to create that face to face conversation. Sure it is fine to snapchat, my girlfriend is my best friend on snapchat. However, you are right there is a line.
Try not responding as fast... or at all sometimes. Let her know that you don't want to be on your phone as much, and slowly limit the snapchating and texting. I went through the same thing, I honestly just stopped looking at my phone as much.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
