I moved into the spare room years ago, and there is no way I could go back to sharing a room with DH. He snores like a train. He says I snore too, but that it doesn't bother him. Well lucky him is all I can say! I really cannot sleep through it. I used to be able to cope, just about, if I got to sleep before him, but then I'd wake needing the loo, he'd be snoring loudly and that was my sleep wrecked for the rest of the night.
Now I have a whole double bed to myself, no-one rolling over and taking my half of the duvet with him, I can sit up and read for as long as I like, I can have music playing softly to get me off to sleep, have the fan on, the window open. You get the picture. As Gma29 said, it's bliss
