My GF (Sarah, 29) and I (M, 28) have been dating for 5 years, and I wanted to go on a vacation with her to celebrate. I planned the trip for several months (of course I shared my plans with her), and decided on skiing/snowboarding/other winter activities in CO.
The activities seemed perfect, and I was looking forward to this for months because I wanted to propose to her at the end of the trip.
5 days before the trip, Sarah dropped the ball on me that she invited 2 of her friends to meet her there. I was upset because I wanted to spend 1:1 time with Sarah for our anniversary. I feel like it was plain and clear that this was a trip for just us. Even though I expressed my concerns, Sarah insisted that her friends already made plans to come and won't back out.
I decided to accept this because there was no way for me to force her friends to not come (I wish I fought more on this). I figured we could make some changes to our plans, and I would still be able to propose to her privately. Sarah essentially blew me off for her friends and we didn't get any private time.
