Well, because of our history, we will forever be suspicious and think the worst. Lovely that we are programmed that way. I am sure he is telling the truth. I know my H constantly sleeps through the phone, the kids, a lot. When I work overnights, he sleeps in the hall on the floor between their rooms because he is worried that he won't hear them.
Can you ask him to call before he falls asleep? I agree with hurt, dig deep and think of your gut. I am sure its nothing but sleep.
