Oh, Amanda, I'm glad you finally wrote this. I knew from Facebook that you had lost him, but I wasn't lucky enough to have really known him. And now I feel like I do. One thing is for certain---he was exactly where he was meant to be.
The ones who go suddenly just tear our hearts out. But in retrospect, it seems as if he would have chosen that way---living life just the way he wanted, with the person he loved the best, right up until the very end. No suffering, no decisions. Just a humongous hole left by his absence. But with each day, and certainly with your eloquent tribute, you are filling that space with those precious memories that are yours forever.
