I am pretty upset with my girlfriend for her decision to postpone our trip that we take every year.
Oh geese. Is it really that bad for her to postpone the trip?
I'm not really angry at her, I just hate that our standard vacation is postponed.
Being annoyed that something you usually do getting postponed is understandable but you shouldn't get too upset by it. It's okay to postpone when something else urgent comes up. Hopefully you don't have to wait too long to get your vacation started.
I guess adult life is more complicated than what I thought.
Try to give your girlfriend some slack on the vacation. Sometimes things come up and you are just not able to make pre decided on dates.
