Been a lot of these in /r/askseddit lately -

"Girl stopped texting, what to do?" "How do I get this girl to text me back?" "Texting went cold. Help!"

So, here is what to do:

Move on.

This is a great place to keep working your abundance mentality. There are so many people to text! She isn't that interesting of a person anyway if she isn't talking to you.

Instead of concerning yourself with how to get her to text back, concern yourself with your over all text game so the next girl won't go cold.

I know it sucks, because you really wanted to go out with her. It's why you want askseddit to help you out. But that is likely the exact same reason as to why it went cold - you were too needy, DLV, and she doesn't want to talk to you. But don't worry, because someone else does. Someone better.
