Try to remember love NEVER DIES, IT GETS STRONGER !
You will always have the memories, the good times, the laughs, the jokes, all the experiences that made the relationship special.
As time goes on it will get easier - I mean you will be able to deal with it through the great memories and experiences that you will consistently re-live the rest of your life. Be sure of this, life does go on, it's different for people everywhere, but it does go on through memories and thoughts at the very least.
Honor them by remembering all the good times and lessons learned, that is what they would want
