Love life and death

If it is a break up - you find someone new who treats you better and you realize the relationship before was infatuation. Not love.

If it is friendship - you make new friends. Ones that will stick beside you through thick and thin. And you realize what real friendship is.

If it is death - I am sorry to say - you don't. Time may make it a bit easier but they will forever be an empty place in your heart.
