AIBU to be upset with my other half?

[CookieDough2017]

My OH was at the pub watching the football with his dad and brother most of the day and turned up 1 hour late to my birthday meal with his family because his brother had way too much to drink.

Am I being unreasonable to be upset with him?

Seems harsh you haven’t had any replies!

Totally reasonable, he shouldn’t be late for your birthday meal. I hope you’re feeling better now

I'd be annoyed too, although it sounds like an issue with his brother rather than him directly. Did he let you know in advance he'd be late?

No he didn’t let me know. I just carried on and ordered food for my DD. I wouldn’t mind but his brother is 30 years old not 18!

Yanbu I'd be upset too.
