As a fellow motorcyle rider, I can empathize with your loss, but the only thing that can fill the empty spot is, strangely enough, the good memories of that which you have lost. Focus on the things that make her you true and only love, the smile, the sound of her laughter, and all the other things that so endeared her to you that you decided to spend the rest of your days with her.
There you will hear her speak to you again, and console you in your sadness of missing her.
That, and I hope the AG there presses every button to get the murdering SOB tossed in the poke for life.
