AIO for feeling really hurt after my best friend canceled on me two weekends in a row?

Last weekend, my best friend canceled our plans. We made plans again for today (the Fourth), and this morning she texted me:

"Morning- ended up getting invited to a day thing OT- so ima do that. Sorry 🫣 We definitely gotta link this week though - cuz i owe u."

The "I owe you" part is because she already canceled on me last weekend.

I'm not upset that she got invited somewhere else. I'm hurt because it feels like our plans are the first thing to get dropped when something better comes along. I had already planned my day around seeing her.

We'd also been talking about renting a pontoon boat together for my birthday next weekend, and now I'm honestly questioning whether I should make plans that depend on her.

AIO for feeling rejected?
