Annoyed with bridesmaid

One of my oldest friends sense middle school. I bend over backwards for her for her wedding 2 years ago. I was a bridesmaid but her maid of honor sucked and didn’t plan or do anything. I stepped up and paid more of the shower and the bachelorette party was planned by me and her other bridesmaid had zero money so I got stuck paying for her and had a fight with her months after trying to get her to pay me back. Now it’s my time and she’s the only bridesmaid in my group that doesn’t have kids. All the girls got together months ago and talked about June 5th working for everyone for the Bach just nothing was set of what. We finally figure it out a month ago and she can’t come because she’s in another wedding now which is the matron of honor and they planned that brides shower the same day.... my shower is next week. She just texted me last night and asked what time my shower was and what time does it end.
It’s a shower, I have no idea we have the hall for the day?!? You should be involved with this it’s at 2. Like she has showed me she doesn’t care. I’m so understanding if you tell me what but she literally didn’t care about picking out a dress so she just ordered one that barely fits because she didn’t care to actually measure herself from azzazie. I kinda just flipped on her last night because I’m just tired of her saying she’s busy. Everyone is busy. You don’t think my other bridesmaid that has 4 kids all in sports and the breadwinner isn’t busy?!?!? Like she’s just selfish and horrible planning because now she’s not sure about the shower next week!
