Stay in bed, or get up?
And if stay in bed, then for how long before getting up?
And if stay in bed, but putting on a light to read is out of the question, then read the phone?
And if reading the phone disturbs her, what?
Lie awake fidgety, while unsuccessfully getting back to sleep?
And if, in getting up, she is disturbed and asks where I’m going?
Or if, in getting up, she is disturbed and asks if she was snoring, then say what?
Or if I successfully make it downstairs and read for an hour, but then she comes down (at 4am) and asks why I’m awake, say what?
