Would you want an invite with this news?

My boyfriend and his friends have planned a guys trip to the beach about 3-4 hours away. It’s been a few weeks in the making but they have a guys weekend trip every couple months and go out without their girlfriends to the club or whatever pretty regularly. One of the guys invited his girlfriend (more like he told her about it and she really wanted to go so her boyfriend said it was okay & the rest of the guys got over it). Would you kind of expect or want an invite after hearing this? Mind you, you’ve only been on one trip together in a year of being together. Or would you not let it bother you?
