I agree with ana too, but reviews or being liked are not the reason why I don't provide explanation for clients becoming ex-clients. It is just to protect my energy and keep it to myself. Even a few messages back and forth with a client delicately explaining why you will not see them again is very draining for me, and I would rather save my finite supply of attention for other things. I am not paid to be a dating coach I am an escort.
The really persistent ones that repeatedly call/text/email, especially when they contact you through multiple channels, are the most important ones to ignore in my opinion. These are usually the ones who don't like hearing 'no'.
