I am also the snoring partner. I ended up having a sleep study done and I've now been using a CPAP machine for the last few years, it took care of my snoring and improved the quality of my sleep significantly.
My partner rolls me (yup) to the side or gently wakes me up so I can change position or maybe blow my nose or something. I easily fall asleep so they know it is not an issue. Sometimes they go to sleep to the couch which sounds awful to me but which is merely an excuse to watch a podcast, cuddle with cats and use a softy-soft blanket.
Now, I also try to deal with it. As a snorer I try to never miss my allergies treatment, be sure to stay warm, drink a hot drink before sleep and maybe read an e-book before my partner falls asleep so I know it would annoy them less if I snore.
My partner snores erratically and sleeps in the spare bedroom. We both sleep better for it but we are working for a better solution through diagnosis.
I snored that disrupted my wife at night. I got sleep tested and found out I had Sleep Apnea. A quiet CPAP machine solved my snoring and helped both of us get some rest.
Not the sexiest thing to wear in bed tho.

We both snore sometimes. If one of us has a cold or allergy, either of us sleeps in the living room. My husband used to snore A LOT and very loud. I asked him to see a doctor and he got surgery, air was not really flowing through his nose since birth. The snoring got soooo much softer. We also added an air filter in the bedroom.
