I [M22] have been planning a ski trip with my girlfriend [F22] and her friends. This trip is an annual tradition for them, and I was the outsider/+1 in the group. I wasn't involved in the planning and was not part of their group chat, relying on my GF for all the details. I trusted her expertise to ensure any pertinent info would be passed to me. I knew we were going to Tahoe, but the specifics were unclear for months until the AirBnB was booked.
Once booked, I pre-emptively searched for the resort's lift passes and was shocked to find out that the lift passes for the ski resort were around $600 for 3 days, 3x the amount my GF had mentioned. It turned out she and her friends had purchased a pre-season pass at a significant discount, something I wasn't informed about at all even though we'd been communicating about this ski trip for around 3 months! I frantically searched for the pass online, but the last chance to purchase it was around a week before our conversation.
At this point, I was furious. I felt that this should've been the first thing communicated to me once I was going on this ski trip. I ended up angrily confronting my GF over the phone, explaining that her oversight was inconsiderate of my time and money. The discussion escalated into an argument. I called her inconsiderate. Regrettably, I raised my voice since I was quite mad. She ended up in tears since I mentioned I was considering canceling the trip altogether. She felt I was being overly punitive and called it an overreaction.
AITA?
