TL;DR Girl lets her phone die when we had tentative plans and doesn't let me know if she was coming or not, when she had left the impression she would be. We argue.

I'm just gonna say what happened, and I guess I fouled up by calling a few times.

Hanging out with my girl Monday, she said wanted to come over Tuesday night and go grocery shopping, sleepover etc I get a text from her around 1730 saying she was still at work. OK.

I expected her to call or text me when she gets home, but all quiet on the Western Front. She hasn't really ever flaked or anything before, so I was surprised. I called a few times, also texted asking if she was still coming. I go running, HOOYAH

So I get a call with her around 2200, she says her phone died. I was confused because her phone had still been ringing, but I also believe it because she hadn't been active on Snapchat and this girl snapchats all the freakin' time. She has a bad habit of letting her iPhone die on a pretty regular basis, she just doesn't charge it, this is something I've observed and not just a story she's feeding. I chalk it up to her not having a great level of responsibility. Just turned 20 yo female btw. I recently turned 22.

So she says went home, went to the store and then her stomach hurts, idk if food poisoning or cramps. Not sure if it's BS or true, but either way I don't see how any of it excuses not sending a courtesy call or text to say she wasn't going to be coming over.

I confront her about it, pissed off, she acts like what she did wasn't a big deal and that "she said she would let me know", that she didn't say "for sure". I don't remember if she did or didn't say that but it doesn't excuse giving me a heads up as a courtesy right. She didn't 'let me know" one way or the other. Also peeving me was the day before that, she had really high affection levels and out of the blue said we would be seeing each other a lot more often. Whiskey Tango Foxtrot?

So we end up arguing a little bit but talk for 52 minutes, she ends up sweetening up and sends me a couple snapchats, one saying sorry with a heart emoji and another where she drew our names in cursive with a heart between them. Oh, and I did mention how my time was valuable and she wasn't respecting me.

We are supposed to judge things by the actions, not really what she says.. right? At least that is more important. So are mixed signals normal like this? It's been 3 months exactly. Am I right to think she is immature or maybe unreliable? Am I wasting my time? Overreacting? I would think if she cares as much as she says, says she's into me and has feelings for me, that she could take the time to plug in her phone for ten minutes and let me know what's up. So I think either she is screwing with me or she's just that unorganized.. wtf.

What did I do wrong and right and what would be the "perfect" TRP reaction.
