Is AUTHOR wrong in the post ? POST : One of my friend's requested our friend group to go to a sporting event or participate in a physical activity for their birthday this month. At that time, I had said that my S/O and I would join at the sporting event and not the physical activity. 

It gets closer to my friend's birthday, and they ask our friend group about ticketing plans. I ask about seating plans, and find out that my friend's S/O had bought the 2 of them nice tickets and they were expecting the rest of us to get whatever tickets we wanted and meet them during half time. I said that would be fine because I expected my S/O and I to get tickets together, so I wouldn't be sitting alone.

Unfortunately, my S/O has a very hectic work life and ended up having to work that day. I texted my friend happy birthday and told them that I would be skipping the sporting event because I did not want to go and sit alone and only see them for the 10-15 minutes of half time. I asked if we could meet up before or after the game instead. 

My friend later sent a very cold message and did not acknowledge the possibility of meeting up for before or after the game. They haven't responded to my texts since, and I don't know if I made the right call. 

AITA?
