I'm so upset?! :( bad friend?

So a few weeks ago my best friend met this guy on a dating app and begged me to go with her even though I had work the next morning to a town an hour away to go meet him. I did. The guy introduced me to his friend and we ended up talking just a little bit. 

So when he asked if we could all do it again this weekend, I was so excited. My friend promised she'd come. I just got out of a very absuive, emotionally and psychically, relationship, and she knows this... so this was so exciting to me. I haven't wanted to date or feel pretty in a long time. I don't know why it meant so much to me but it did. I bought a new outfit. Some new makeup. Was super excited all week and couldn't shut up about it. Wasted my weekend looking forward to Sunday so hardly wanting to go out or anything. I spent all this morning waiting for her to message me, trying to get in contact with her, doing my makeup, my hair, etc....

But when I tried messaging her, she didn't answer. I called. texted. Etc. She then tells me she's 3 hours away from where we live, but can leave now and be home in time. I tell her to do so and she stalks another hour and then says to me I should just go alone, and makes it sound like she's doing me some huge favour. She tells me she doesn't like the guy she was with so she would just drop me off. Anyway, this goes on for hours and hours and it boils down to: she's not coming. She hangs up on me when I try to ask why and logs off Facebook. 

I confused the poor guy trying to explain what was happening and when we were coming so much that eventually I just told him another time. 

I'm really upset cause I was really looking forward to this, I cried off my makeup out of frustration... 

She's still ignoring me. I didn't need her to come, but she could've told me she was going to ditch days ago... 

What should I do?
