So then, I had an appointment this evening with a provider I've seen several times in the past.  All seemed to go well on previous visits...I had a blast, she seemed to have a blast, and everyone smiled at the end.  In fact, through this weekend, everything seemed to be just fine.  Anyway, as I'm driving over in the rain (which likely didn't improve my disposition on the matter), I get a text, the gist of which is "I feel I sent you some mixed signals, and now I'm uncomfortable meeting."  And that's pretty much it.  I certainly don't feel I've gotten any mixed signals, and it has seemed to be a pretty straightforward provider-client transaction so far...I know I don't have any expectations other than the usual arrangement.  I tried both phone and text to get something along the lines of a reason....I'm definitely not in a frame of mind to try to talk her out of it, I would just like to know why.  I'm polite, my hygiene is good I believe (I pay attention to it in any case), I pay cash, and I don't have any unusual kinks (actually, I'm pretty routine I suspect), we've done well together in the past I believe, and she accepted the appointment this past weekend.

Now then, I know it is absolutely any provider's right to refuse to see anyone she is uncomfortable with, and I definitely have no argument with that at all.  If it was a first visit, I likely wouldn't think twice, but as I've said, we've seen each other several times now.  In the grand scheme of things, I also know that it's pretty much check the box and move on with life.

Now the question.  I'm pretty annoyed at the moment (well, pissed off is a better word for it), I was looking forward to a fun evening and this strikes me as a pretty straightforward flake, but should I reasonably expect the politeness of some explanation....not a lot is required, no drama, no back and forth, just something beyond the one liner blow off I got....?

I'm sorry to hear that happened to you. Definitely sounds like a crappy conclusion to the evening. I'd say you certainly deserve more of an explanation...however, I wouldn't expect one. It is possible this provider grew feelings for you/felt you were growing them for her, or that at the last minute she found some information (i.e. From a reference or a blacklist) that left her uncomfortable with seeing you. If the latter is the case, I doubt you'll hear from her at all. If it's the former, hopefully she will explain herself, or you can evaluate whether you've said or done anything that could be misconstrued as becoming overly attached/emotional. However, there's also a solid chance the provider is simply flaking out, and so I wouldn't hold on to any expectations that you'll hear from her again.  
If you're certain you haven't said or done anything inappropriate, or that could make her think you're becoming too attached, then I would just move on and forget the situation. Remember, the best way to get over someone is to get under someone else

Common sense thoughts all around....thanks.

I would think though that if it was an question of some budding emotional attachment (either hers or mine), simply saying so would be a far more polite response than the blatant blow off.  I haven't seen anything from her that would lead me to believe that she'd developed feelings (but truthfully, I can be thick as a brick in these things), and I'm not aware of anything I've done to give her the impression that I'm growing unprofessional feelings, but I suppose you never know how things can be taken, and I'm a friendly guy by nature.  I can't think of anything dark in my past, and we have seen each other often enough that she knows me...so I can't imagine anything coming up there.

So, I'm pretty certain that I haven't said or done anything inappropriate....and definitely not intentionally.  I think what gets me is that I find this stunningly disrespectful from someone I'd thought better of.

I really like that expression by the way....so I guess now it's time to search for the right person to get under....

Very eloquent, and very well put.

I couldn't agree more, sounds like you are owed a more in depth explanation, but likely won't get one. It's like going out on a few dates with a girl, and all of sudden she stops returning calls or texts. Does she owe you an explanation? Sure. Will you get one? Probably not.

We women are somewhat funny... In case you missed it, haha.  

It sucks, but it's reality. Sorry to hear that you weren't able to get your groove on!

That does seem to be the prevailing thought....and I'm rational enough to know I'm no closer to understanding women than I was at 18 years old (not that I can remember that far back....

It is what it is....thanks much....

Best to not try to figure it out.  She'll either respond back or she just decided at the time she didn't want to see you again after all. Or it may have nothing to do with you personally and she just thought of something quick to say. One thing I've learned over the years is to expect the unexpected,and things can change in a heartbeat.

Women!

Met a lovely lady in N Raleigh.  Had 6-8 quality visits.  Great conversations...Great rapport.  All of a sudden my emails were not returned. Tried to replay some of our conversations to see if I had strayed boundaries!  Could not come close.

2 months later I ran into her at a local gym.  We discretely and mutually approached each other outside where it appeared safe.  I smiled, shrugged my shoulders and asked "What Gives"?  Her response was "It's not what it appears!"  About a month later she sent me an email and consented to visit.   It turns out she was being stalked, and threatened to be outed.  Her only recourse at the time was to cut ties and fly beneath the radar.

Like Steph mentioned in a previous post , you just never know what happened irl,and what was on her mind.

Carry on comrade!  Plenty of attractive ladies at this beach!

How right you are, and in the end I suppose I've been pretty fortunate...this has only happened twice in the last couple of decades...
