<human>: Can you give me the gist of the text in a nutshell?

I met a girl at work that I have a lot in common with. We've been hanging out for about a month or two and we get along great in person. But it's happened three times now that I'll invite her to do something and she'll text back saying something like 'Yeah, I'd love to! I'm busy do XYZ right now, but I'll let you know when that's over.'   
  
Except then she will text me hours later about something completely irrelevant, like 'oh look at this cute picture' or something with no mention of the fact that I was expecting we were going to go to beach, or go shopping, or whatever.  
  
It bothers me that she ignores my invitations and then glosses over it later. I get excited thinking about the plans we've made because she follows through 90% of the time, but the times that she doesn't is seriously annoying because I get really excited and keep waiting for her to text me. It's hard to pretend I'm not irritated with her. She just did it again today. I don't event want to respond to her right now.  
  
I feel like maybe she just doesn't want to go but doesn't want to hurt my feelings. She's a people pleaser and is really bad at saying things straight. I'm just looking for advice on if I should ignore it or tell her that it's honestly getting annoying. The thing is, the only plans she ever ghosts me on are the plans that I'VE suggested. If she suggests it, she shows up. It's annoying but she's pretty awesome besides this and I haven't had a friend in maybe 6 or 7 years so I don't want to ruin it and we honestly have a great time when we're together.  
  
It also makes me wonder how many things she's enthusiastically agreed with me on that maybe she's just been lying about to avoid telling the truth that she has a different opinion.
<bot>: My friend feigns interest in and then ignores my invites and glosses over it later but shows up to all the things SHE wants to do.
