I have a few reviews here on TER, and numerous okays from providers on a major verification site.  I set up time with a provider a couple of weeks ago.  We had a great time (I thought). Asked her if it was ok to submit a review here, and she was excited about the prospect.

Wrote the review, and it got posted.  High scores, and complementary juicy details.  Sent her the link, and she wrote back that she was very flattered and grateful.

In the meantime, the provider and I exchanged some pleasant emails, including her writing some nice things about our get together.  Know at least some of it was selling, but ok with that.

Asked for another date, and she declined because of a doctor appointment.  No problem.  Let a few days go by, and asked again.  Sorry, going out of town for a week, see you when I get back.  Disappointed, but no problem.  A couple of days later, a buddy of mine on the local boards thanked me for recommending her, and had just seen her the night before.

Emailed her asking if she was still out of town.  Yup.  WTF?  Called her on the lie, asking why, but haven't heard back for several days.

I can understand if she didn't have a good time with me, for whatever reason.  But why keep up the false pretense of emailing etc?

I am trying to let it go, but for my own education, would have liked to know why she's half flirting and half avoiding.

Any theories?  

...so I'd say stop torturing yourself because you'll never know.  Just move on and enjoy the many girls who'll be glad to see you.

she really was out of town but had a date (maybe extended) with your friend and came back to town for that.
Maybe she already had a date with your friend but didn't want to take on any more appointments and thought for whatever reason it'd be easier to say she'd be out of town.
Maybe she planned to go out of town but didn't and then forgot to email you back.
Maybe she doesn't want to see you.
Maybe you said something to her in email that she didn't like.
All you can do right now is speculate. It could be anything. If you really like her, see what she has to say. If not, move on.

All the email exchanges after a session are just wasting the providers time. Maybe one at most is enough. She probably finds you more work than its worth to her.

Good answers from all.  I think some observations are spot on, and will follow the advice and move on.

Let's start with the fact that the very nature of providing is deception.  A provider pretends to be your lover for the length of a session, that's what you're paying for--a performance.  Why did she see someone else instead of you?   Maybe because you got outbid, maybe she disliked something you did, it could be anything.  She may have fed you a story to avoid hurting your feelings.  She's not your girlfriend so she's not obligated to explain why she doesn't see you on a given day.  

When you "called her on the lie", you crossed an important personal boundary and she's probably not going to see you now.  You should forget her.   Sorry,  --z

Ladies have a right to their personal lives.  It's none of our business what they do on their own time.  Her BF or mother might have been in town or whatever.   You set her up by asking if she was out of town...  knowing she wasn't.  Challenging her on her little white lie, pissed her off.  
Some ladies are more concerned about guys getting clingy...  come off as almost despirate.   I'd say move on.  If you had a real good time, circle back after a while & ask again.  

I prefer to rotate among a few Favs, rather than burn out with one.

Over the years several gals have suddenly and without any explanation cut off communication despite the fact I know they were still working and even posting ads on TER and elsewhere.

There's no use in fretting over it, it's just one of the problems that comes along with the hobby.

It's a big ocean out there.

Move on.Move on  Forget her and move on.  I would never contact her.  Remember you would need to take an initiative for what you are seeking and wanted.  There are always  endless supplies so.
Move on.   Remember her pussy is to make money not develop a relationship. Almost everything is related money and wether you are Tom Cruse or tiger Woods,  anybody. as long as you have the money , they  
will treat you nice.  That is what it is.  MOVE ON...

Being rejected by a hobbyist can happen to us girls as well. I sympathize with you on this, but also know that there could be many reasons she didn't want to take a second appointment with you. I can almost guarantee it wasn't you calling her out on a white lie, or emailing too much,,,,It was what actually took place within the appointment. Most providers, in my opinion, will make an immediate assumption five minutes after you walk into and out of the door, about seeing you again in the future. We all have our preferences, and we all have our favorites. It is hard to find a good, solid chemistry that will last for multiple or long -term "relationships" in the hobby. But, as the others mentioned, there are definitely MORE FISH IN THE SEA.
So try another lucky lady and enjoy yourself. No need to fret about one provider when there are SO MANY others to choose from. Agreed?
