Stop Snoring Remedies

We both stay in a pretty small, cramped room. Her boyfriend sleeps over a few nights a week. Recently he began to snore really loudly! It is so loud that I wonder if the room next to us can hear it! I’m not exaggerating.

Even though she’s lying right next to him, she can sleep through it! But I cannot sleep at all! I’ve tried burying my head under the blankets and pillows, but I end up suffocating myself. One night it was so bad that I just got up and slept outside in the common room.

I’m a college student that needs rest so I can be energized for classes the next day. I tried addressing this problem with her, but she just sort of brushed it off, saying that I should talk to him. When she told him, he just said that he couldn’t do anything about it because he has tried remedies, but they don’t work.

Am I being selfish since I’m the only one it disturbs? I don’t want to hurt anyone’s feelings, help please!!
BTW, I know for sure he doesn’t drink. Haha.
