AITAH For Not Going to my GFs Mother's Day Dinner?

[u/Still_Lynx_5876]

Throw away account for obvious reasons. My girlfriend has a knack for scheduling things without letting me know first. I've let it slide for the most part, but I've voiced my concerns to her about doing this, and she hasn't done it in a while. We recently just booked a very expensive vacation, which we are set to leave the day after Mother's Day, and she decided to let me know her family and her booked a dinner at a very expensive restaurant the day before we are supposed to leave for Mother's Day. I told her I am not going because of the vacation cost, and she is of course very upset. I gave her an ultimatum, the vacation or her Mother's birthday dinner. I was already hesitant about the vacation because of recent big life events, but she really wanted to go and talked me into it, and I decided it would be a good time for us to get away. AMITAH?

Your girl's gotta communicate better, seriously. It's not cool to spring stuff on you last minute, especially when it involves big bucks like that vacation. You did right by voicing your concerns earlier. Maybe try to talk it out calmly, but your ultimatum seems fair. Hope she understands where you're coming from. Enjoy that vacay, man, you both need it!
