I am sending this out to get a feeling if I am wrong or not.
I see this new independent and we have a great time.
Few days later she asks for a nice review - which I happy oblige.
Few weeks later I try to see her again - she cancels on me at the last moment.
Then again she moves in another location.
And she doubles her fee and does not want to see me at the old rate.
Am I wrong to feel a bit frustrated ?

were u waiting this long to bring it up?

Just move on....there are plenty of other providers out there. You were used, but I'm not surprised.
