AITA for canceling the entire evening

My friend and my boyfriend planned a surprise dinner for my birthday on a Saturday. A week before the dinner my friend moved to reservation to Sunday at 9pm so her boyfriend could come too. We all have work Monday morning but I didn’t think much of it, he mentioned it was late so I told him to message her that day to figured it out because I had nothing to do with the planning and the week went by with no one talking about. The day of my boyfriend messaged my friend asking her to change the reservation because he doesn’t want to be out that late on a Sunday and she can’t because it’s the day of the reservation. So he says he doesn’t want to go out anymore and for me to go alone with just my friend and her boyfriend. Am I the jerk for getting upset by this? I told my friend I couldn’t go because I didn’t want to be even more embarrassed that he wouldn’t go. He had a week to ask to change the plans and now he is mad at me because I’m upset he won’t come to the birthday dinner that they planned for me. My friend changed the date and we can always do it another time but it’s just the premise that he waited and doesn’t want to do this with or for me on my birthday.
