Sleeping husband

JTJKH
My husband started a new job last week he went from working 14 hour days to now working 16-18 hour days.
Both of our kids are gone for the night when I got home today he was already asleep (8:30ish)
I so badly want to wake him up right now to cuddle & enjoy our time alone together talking and catching up but I know he's dead tired he looks so sweet and handsome in his sleep it's so hard to resist! We never see each other or get to cuddle/talk without 1 or 2 kids interrupting or one of us being asleep 
.....ugh the temptation! 
Should I wake him or let him sleep :/
