Hi Reddit, I (24F) have been planning a birthday party for my boyfriend (24M) for about three months now. The party is in six days, and I sent out invitations a month ago. The guest list is pretty small, around 10 people, and I really want this to be a special day for him since we’ve only been dating a little over six months, but have known each other since childhood. I sent out a reminder to everyone recently, and my friend (22F) replied that she and her boyfriend (23M) wouldn’t be able to stay long. Originally, she told me she didn’t work that night and would be able to make it. When I asked if she had other plans now, she said yes, that she has prior obligations and a busy day overall. I want to say that I really love my friend, and I’m not upset with her about having a busy day full of plans. I even offered that if she’s too busy to make it to the party, we could plan another day just to hang out. She doesn’t already have any plans to come spend time with us outside of the party. That said, I’m seriously considering uninviting her altogether. It might sound selfish, but here’s my reasoning: The party is small, and I’m worried about the Domino effect: if she shows up at 4 PM and leaves after just an hour, others might start leaving early too, and the whole party could fizzle out way too fast. The plan was for everyone to arrive by 4 PM, and surprise him with it around 4:30 after kicking him out of the house earlier to prepare. If she’s gone early, it might ruin the atmosphere and make the party kind of a flop. AITA for thinking about uninviting my friend because she can’t stay long and might cause the party to lose momentum? Should I just go with the flow of the day and not worry about people leaving early? Thanks in advance for your thoughts, and any advice on how to handle this correctly.
