AITA for reminding my friends to buy tickets

I 19F, have been reminding my friends (19F x3) about buying music festival tickets for the last month. Every time we see each other, we talk about us buying tickets for the music festival. Friday of last week, I brought my ticket for the festival. I sent out a reminder to my friends that the prices had gone up so to be aware of that $150 to $198. I was under the assumption that one of my friend has also brought her ticket as she said earlier in the week that she was going to, but she didn’t. One of my other friend in the group chat responded she’d buy it later in the day, so I trusted her good will. However, a day after, I reminded them once again only to find out that the tickets were waitlisted now. I’m the only person who actually has a ticket and one of my friends now is saying she’s going Sunday instead of Friday as planned. Since then everyday I’ve been reminding them to join the waitlist or try to find a resales to maybe get a ticket that way. My friends have been saying they think they’ll get off the waitlist but I’m preparing for worst case scenario. As the only ticket holder, I wish I was told that they weren’t actually gonna buy the tickets when we said we were as the tickets can’t be refunded and I would like to have a back up plan. I’m being told I’m too pushy. AITA?
