What Happens When We Die?

When my husband was dying he asked 
"What happens after I die? Is there a heaven?
Will I see my mother there?" 

I said "No, of course not. There is no heaven. 
Dying is peacefully moving into nothingness.
You will never see your mother again." 

He closed his eyes and sighed and said:

 "Oh! Good! That's a relief!"
I knew this was the answer he wanted to hear. 

What surprised me is that 

he trusted my words implicitly. 

That he believed I would know.
