Bridesmaid trouble

My one bridesmaid, who I love to death, has been very sketchy with me lately. I sent out a group chat in the very beginning of December telling the girls that I wanted to have a bridesmaid day February 22nd to look at dresses for them and my mom wanted to see them to talk about my bridal shower and all of that jazz since half live out of state. Back in December this bridesmaid said how excited she was and that she made sure she requested off from work and everything. Two weeks later I see her and she says “so when are we doing that bridesmaid thing again” with a little attitude, so I said 2/22 (she lives in my area, not an out of state bridesmaid). Last week my other bridesmaid in Virginia told me she couldn’t make it, completely understandable because she’s in medical school on her residency and I would never expect her to miss that for dress shopping. So I texted the problem BM and I was like hey just checking in seeing how you’re doing and making sure you’re still coming the 22nd. She said she was trying to find someone to cover her shift, even though she told me two months prior that she requested off already. She has bailed on me three times already on other bridal occasions and make excuses which I found out were lies. I texted her again and I said if you don’t want to take part in being a BM I’ll completely understand, I’m just getting mixed signals from you and I want to make sure this is something you want to do and how I’m not offended if you don’t want to be one anymore, yes I’ll be disappointed but I understand. SHE LITERALLY READ THE TEXT AND DID NOT RESPOND. It’s been three days now. Do I text her again and see what’s going on or is this just me having to accept that she doesn’t want to do it. Sorry for the long probably confusing message but I’m lost!
