When I had a long-time partner - some time ago - the one thing that really got me and drove me crazy was...snoring. Every single night the guy had to snore his way through his sleep pattern that sounded like a bulldozer drilling holes through our walls.
He tried all sorts of things to try and stop the snoring and I know he felt bad, but nonetheless, I was the one that suffered the most - practically no sleep!
If I managed to get a few hours, that was great and I would stop the snoring for a while by nudging him to turn over.
People suggested that we sleep in separate rooms - we did and I still heard the noise, because late at night, every sound can be heard in a magnified way.
We eventually parted company - not due to the snoring - and slept in separate houses. That solved the problem of the snoring alright, but other problems arose then and nothing to do with snoring.
So nowadays, I have to say, in a crazy kind of way, I MISS THE SNORING ! What does that say?
