My DH snores like an old buffalo, and tbh we have had separate bedrooms now for some 15-16 years. Since our DC were at junior school. I don't think I would still be married to him otherwise.
For the first 10 years we were living together, he was OK, then he hit 35-36 years old, and started to snore.
It got heavy and loud quite rapidly. He wasn't overweight either, he just suddenly started snoring, and as I said, he got loud quickly! We didn't have a spare bedroom, and it drove me batshit. I had such horrifically broken and fractured sleep, and it was making me angry and fatigued and upset.
I started sleeping on the couch, but our DC got up at 7am ish and got themselves breakfast and put the TV on... so I never got a lie-in.
I would be resentful that I was ALWAYS woken up at 7.00-7.30am even at weekends, during school holidays, and days I wasn't at work! Meanwhile DH snored away, and slept blissfully until 10am.
Sometimes I would deliberately knock and bang about at 8.30am near the bedroom to wake him up. I was so deeply resentful! I thought 'why should YOU get a fucking lie in?!'
He would NOT seek help, and he just said 'I can't help it can I?!' 
Anyway, so we moved house when the DC were about 10-12, and had an extra bedroom. My own room..... Bliss.
It's just lush. Such blissful unbroken sleep, and my own little sanctuary. I could never go back. If and DH and I split, or he died, if I ever got with another man, I would never share a bedroom with him. Probably would not even move in with him tbh!
Sorry @TeenLifeMum tl;dr and not helpful to you! There is really no other answer apart from separate bedrooms!
