It drives me utterly mad. DH falls asleep every single evening on the sofa - often while I'm up putting the kids to bed (8.30-9). Or if not, by 9.30 at the latest. So I turn the TV up enough to hear it over his snoring (but not enough that he wakes up, turns it down - then goes back to sleep!!) So I go to bed alone - and more often than not wake up alone too, as he's either got up early, or gone to the spare room.
He gets up early for work but I get up about half an hour later, so I can understand he's tired - but his hours don't explain his sleep patterns. And it happens at the weekend too.
Things aren't good at the moment, so I think this might be a deliberate - or unconscious - way of checking out of the relationship.
I'm unhappy - and lonely - in my own marriage. But I don't know if this is IT. The kids find him increasingly grumpy - and can be upset by his moods. But they also love him.
I don't know what to do... Sorry, think this is about more than sleep!!
