I [32M] want advice on how to talk to my girlfriend [54F] about her telling me last-minute about a vacation

r/

I’ve been in a long-distance relationship with my girlfriend and havents seen eachother for 2 years. We text and call every day, but haven’t seen each other in person during that time.

Yesterday she told me, while already at the airport, that she was leaving on a trip with two friends. I was surprised, because she normally isn’t spontaneous. I would usually let her know a few days ahead if I made plans like that, so I felt unsettled when she only told me at the last minute.

My question:
What is the best way to bring this up with her so that I can explain how it made me feel, while keeping the focus on healthy communication rather than making her feel restricted?

Length of relationship:
2 years long-distance, no in-person visits during that time.

TL;DR:
My girlfriend (54F) told me at the last minute that she was leaving on a trip with friends. I (32M) want advice on how to discuss it without it sounding like I’m trying to control her.
