I lost my floof mcgoof (my lovely pet rabbit) last year. I still cry when I remember him. I loved him and still love him so much. It's okay to keep the background. The heart never forgets those that have touched our lives. Your beautiful boy was so lucky to have such a wonderful friend like you.
For me, I try to think about my floof mcgoof sitting in my grandma's lap in heaven so I feel a bit better. He always loved being around people so he's definitely keeping all my loved ones who are no longer with me company :,)
And this reminded me of this which I really love:
In every heart that you get to know
It leaves a mark when they come
And a scar when they go
But I guess time's only purpose
Is to heal and to make you grow
Leaving you like a canvass
Of the prints of your soul
