<human>: Can you condense the text into a few key points?

She's never really been needy in terms of communication, and I've been abroad this entire summer. Granted this was the first time during our LDR that I just didn't respond to her because I was busy doing things. I have internet everywhere, so realistically sending a text WOULD have been easy, I do realize. It didn't mean that I wasn't thinking about her throughout it all, but she's upset because I had texted her "I will be awake early! Around 7am, my time, so if you're still awake all the better :)" and then didn't reply to her for a few days. Other than this, we don't have any problems with our relationship, so I'm wondering if this is a legitimate reason for two people to part? Did I screw up that badly?
<bot>: GF got upset with me for seeming like I would respond to her when I woke up, but then not doing so for a few days after.
