Long relationship. need song that fits us? help.?

Okay, conner and I have been together for the last two and a half years and for the last year, we've lived in different states and unable to see each other and I miss him A LOT. We always have this thing where we pick a song. The one we've had for the last couple years has been "comfortable" by john mayer. I need a song that really fits us. How much we miss each other, how far away from each other we are, and how were in love.
