ahhh, gotcha. I wish you wouldn't have responded to her very first text, but that's behind us now. I am confused, however, as you said she'd gone silent today and now you're saying she texted you asking to chat today?
With that as the backdrop then, I WOULD respond to her last text, with a "I wish I could believe that; I'm afraid it's not that simple anymore."
And then go PITCH BLACK until tomorrow morning, including staying out all night tonite.
