That [censored]. If it helps, I doubt you were as close as you think. If within 2 days of a great date she hasn't reached out to you, and when you call she's ready to decline another date and apologize for the mistake and mixed signals.. it doesn't seem like waiting another 5 days would've led to success.
Was your mistake the act of trying to reason and plead with someone who didn't want to date you--or being in a place that you feel the need to reason and plead with someone who doesn't want to date you?
I'm with OverTheRainbow--GAL--until that desperation melts away!
Feel your worth. Maybe she'll see it. If not, others will.
