It's impossible to know for sure what someone is thinking, especially without being able to directly ask them, but I don't think there's anything to take away from Gura's silent periods other than she's busy, forgets, or simply didn't feel like it. I myself easily forget to reply to people IRL all the time, even when it's something important, so I imagine the same is true with Gura.
