Kicked out of the Wedding Party before even being asked!

Ok, so I have a friend who was my best friend in high school and through most of college. She moved away for college about an hour and a half away. Over the last 3 years we have gotten together and talked less and less. Every time we reconnect it’s like nothing has changed, except when her boyfriend is around... They started dating about 3 years ago and it hasn’t been the same since. She often comes back to the state to visit her family (who live 15 minutes away from me), but almost never lets me know. About 6 months ago she called me and apologized for being so distant, and told me all about what has been going on in her life. I totally understood and we started to talk more again. In April I got engaged and FaceTimed her almost immediately. She was so excited for us! She told me that we should have our engagement party on Memorial Day weekend since she would be in town. I thought it was a great idea, since she is one of the only people I wanted in my bridal party that is from out of state. The day before the party she let me know that she would be a bit late because she had just found out that she had to bring her parents to the airport. I told her it was no problem since I figured people would just come and go when they could. The day of the party she texted me saying they were stuck in traffic and would be even later. I just told them to come when they could since the party probably wasn’t going to be over until late that night. It was about 10:30pm and I realized she still hadn’t come. I didn’t get any other texts from her. I just enjoyed my night with my friends and family. The next morning I woke up around 11am (I really needed the sleep lol) and she hadn’t texted me at all. I texted her asking why she never came. A few hours later she told me that they got home around 10 and were tired, so they didn’t come. I was upset. I told her that I planned the party around their schedule and they didn’t even bother to stop by for 10 minutes. She said she would make it up to me and come over the following Friday since they were still in town. At that point I had already made her proposal box and didn’t know if I should still have her in my wedding. I figured I would wait until I saw her again and then decide. Friday came and she came over with her boyfriend and our other friend. The other friend and I were having a good time drinking wine and talking. My friend basically just sat there silently with her boyfriend on her phone. All of a sudden she gets a call from her sister and jumps up and says she has to go and get something for her sister. Our other friend was bummed since they had only been at my house for an hour or so. My friend insisted they leave and seemed rather happy to have a reason to go. This was a month ago and I haven’t heard from her since... So, I asked one of my closest male friends to be my “bros-maid” and he was ecstatic! I’m so happy I didn’t let my forgiving nature get in the way, and now I have an awesome and supportive bridal party! Anyone else have a similar experience??
