Do I have a right to be annoyed at my best friend/bridesmaid

So my best friend, we'll call her Ashley, agreed to be a bridesmaid for my June wedding last June. My maid of honor starting planing my March bachelorette pretty early and told all the bridesmaids the plan in August or early September.Yesterday, Ashley texted me that she won't be able to make the bachelorette because she can't afford it. Understandable and I completely respect her decision - I don't want people going broke just to attend my party.Later though, I found out the reason she can't afford it is because she's planning on attending her friend's (my ex best friend) birthday party in Nashville in June and is claiming she started planning the birthday party before she knew about my bachelorette.So I'm upset for a few reasons. Biggest being that by agreeing to be a bridesmaid, she knew a bachelorette was coming (well before she knew of the birthday party). Again, if you can't afford it you can't afford it, but I feel like she's prioritizing this girl's birthday party even though she knew of the bachelorette in August.Now I'm left feeling hurt because I feel like second place. Birthdays come every year but wedding festivities are once in a lifetime and special to me, especially since I don't have a lot of bridesmaids to celebrate with.All in all, I'm really bummed she can't come. I don't want to sound selfish but I'm wondering do I even have a right to be annoyed by her trip prioritization. Anyone have any similar experiences? via /r/weddingplanning https://ift.tt/3bi4xsP
