Don't mind you coming back at all
There is no need to be all red faced about snoring, the best of us snore, even if we don't know it.
I think you need to go back to your GP and ask what can be done to help now!
There is no reason why you can't have a relationship, others do.
Is your GP one of those that will listen or are they one of those that dismiss you because they can't be bothered with what appears trivial to them?
May be trivial to them, but to some snoring can be a BIG issue.
If they think you do not have Sleep Apnoea, what do they suggest to help with the snoring? I think you need to go back to your GP and ask the question. I also think a home sleep study might not be out of the question just to rule out OSA.
Go back to your GP and suggest this, just to rule it out if nothing else, then ask where you go from here.
