I've found out that DP has organised a piss up with his mates the night before my birthday. I am actually really pissed about this as I don't fancy spending my birthday with a hungover lump. We usually make a big deal of birthdays and he is usually very considerate so it's shocked me.
I originally suggested a group party (all the couples basically) for the same date but no one was bothered, now that it's men only they're all jumping at it.
So aibu to be pissed off that he plans on being hugely hungover on my birthday?!
