It's been two months. I hope this girl didn't go missing or something horrible like that. But the alternative explanation isn't favorable either: she got a new phone number and somehow forgot to tell everyone, or else no one was sufficiently curious to learn about it. I hope they see her every day and have little occasion to bother with a text message, if that's the case. That would be a good scenario.
One guy didn't believe me when I tried to explain someone else had this number. He kept saying, "Okay, be that way." I didn't want him to get mad at the young woman (I've learned a lot about her, from all the messages I get) so I really tried to explain this happens all the time, people change numbers. It could be that youth no longer understands how to appropriately use "be that way" in a conversation and it means something else now.
I mean, she sounds popular, based on the kinds of messages she gets. But the fact that no one knows how to reach her sounds like a matter for some concern.
