Dh goes to bed before me due to shiftwork, and every night when I come to bed he is lying down the middle of the bed, head right in the middle, mouth wide open and snoring/breathing on me from the moment I climb into bed. It gives me the absolute rage (not quite but very pissed off) so I get into bed, fluff my pillows up in the hopes it'll make him roll over. Sometimes once Im in bed I pull the middle of the duvet up to cover my shoulder (block his breath) which normally also happens to make him roll over to face away from me.
BUT invariably, once I have just got comfortable, he bloody rolls over again and starts breathing on me again so I have to move.
We dont have a spare room to move into and when I bring it up he gets quite defensive and mentions that I also sometimes snore (when Im ill with a bunged up nose), but I also dont lie there breathing over him every night
YABU - you should enjoy being breathed on by a creature that sounds like it is struggling to release itself from the depths of hell
YANBU - its disgusting and should rightly give you the ick
