Would this make you upset too?

So I'm a freshman in college and my boyfriend is from the state (he's a HS senior) I️ go to college in, while my home state is about 2 hours away. I'm leaving to go home on Monday and probably won't see him the entire month long break unless he visits. We've been together for 1 1/2 years give or take. We had plans last night to have a sleepover in my dorm but it was snowing so I️ told him not to come (for his safety) he said ok, promised me we would do it tonight (Saturday night) instead and went to his brothers (bro is 22) and got extremely drunk (not a normal thing for him). He's been so hung over all morning, he told me he keeps throwing up and that he feels so bad that he'd rather me just come to his house. But we had specific plans at my school of things to do and honestly I️ don't want to sleep on the couch in his guest room, so I️ told him no. I'm really bummed out and annoyed that he made such an immature decision knowing it could ruin our plans. Would anyone else be annoyed? 😓😓
