Bottom line, you have to go with the flow and respect her rules if she black listed you. Don't take it personally. She may come around again in the future. There are more wonderful ladies to meet and have fun with.
I have had to cancel before, but only twice that I can recall. One was a week prior and tried to reschedule for a week later.
I had a situation where a Provider I had seen for over 15 months cancelled at the last minute twice in 7 days and then did a no show three days later. I had seen her at least 15 to 18 times prior to that. Th is was back in October.
She texted me to.apologize in Novenber, I saw her twice in November and gave her some rather nice Christmas gifts too. Then in December she cancelled on me one Sunday and then did two no shows, all this with in 4 days of each other. I was so shocked and a little hurt and a little upset this time around, but never reported it anywhere. She is fairly reputable and the actions were not indicative of how I knew her the first 18 months or so.
We had our falling out, I guess I held on so long hoping to see her because I truly liked her. Not saying that I had nothing to do with her actions, but th e just did not add up. I learned a lot from my time with her, but I should have walked away from that arrangement after October, but I liked being with her too much. Sorry for the ramble, but this is a hobby, enjoy, have fun, and don't let the misconnect bother you too much. You are not out any funds and no harm.
Peace, SORRY for the ramble.
