Am I being selfish?

I'm in a long distance relationship (we live 200 miles apart) my boyfriend is 19 and I'm 16, he doesn't go out very often but he's at a festival this weekend, he's been there since yesterday and I already hate it 😞 I'm terrified he's going to get so drunk and cheat on me or do something stupid, I just want him to go home but I can't tell him because he barely goes out and I want him to have fun but I also want him to be at home talking to me 😫 I just need some advice please 😌
