I've been out for a while but have ventured back for an occasional encounter and wondering both the ladies and guys thoughts on appointment etiquette.

Short backstory... set an appointment for today, texted 15 minutes before to make sure it still worked... texted at appt time, texted 10 minutes later to see if we needed to push appt back, texted 10 minutes later asking if we needed to reschedule, texted 10 minutes later saying I look forward to hearing from her. I understand things happen and plans have to change so not "done" with this well reviewed lady but it leaves me wondering:

1. When should you confirm on appt day and who should confirm?
2. How long do you wait with no response before just considering it a NCNS?

Hopefully I hear from her and can reschedule.
