Thanks Rainbow. That helps.
I was sneaky just now.

I have an appointment scheduled way out at the end of this month that will not work. So I called to reschedule for that week and then casually asked if T was there today. The answer? NO.
But you know what? I feel So.Much.Better!!! T wasn't there today! That's why she hasn't called! So yes, I get to sit with this all weekend, but at least now I don't think she isn't calling because she secretly hates me or I annoy her. I can worry about that on Monday.
