Why snoring can ruin a relationship

I do not want this to seem like a pity party, but I do want to get it off my chest because it is really bothering me. I snore very loudly, to the point where it may wake me up at night and I do not wake up feeling refreshed in the slightest (I wake up very tired).

When I got married, I figured that she would be OK with this issue or at least understand. Whereas we would spend most nights together before we got married (we did have two apartments back then), nowadays I have been sent to the couch more times than I care to remember.

It just makes me feel bad because I feel as though I am upsetting her sleep, but at the same time it annoys me because I am not actively doing anything to make her tired – it just happens. Is there anyone who might have some advice on what I should do? Maybe how to approach the subject? Thank you.

It showed just what I think is one of the differences in the approach there
