Regulars. Here's how I look at it and it works for me. I care about their financial well being so I try to make sure I see them "when no other business is available to them". For that, I get great GFE & sometimes extra services. But, the difference is I  communicated with them that this is OK. So I don't mind if they blow me off, becuase they always blow me off when they see me.

I had seen a providers for about a dozen times (basically whenever she visited DC). It was great the first half dozen times but then her services began to slip. I think I waited too long before I finally confronted her. She got defensive of course, and things were never the same afterwards. I stopped seeing her after one more visit.

I have had two 'ATF's and both experiences ended badly, The other one became too needy and wanted to see me every month (steady monthly paycheck, I guess) so I had to stop seeing her also. After these two, I decided ATF is just not for me.

when it suits you and inflexible when it does not suit you. That is exactly what she is doing. You may be able to be flexible, but clearly it is a concern for you that is unsuitable in this case. Bet she has a "timewasters" statement of some sort on her website. Turnabout is fair play - timewasters (of either sort) get put on the DNS list. Only you can decide when things have hit that point for you.  

I'd just caution that if you are too attached to her, or too invested in "arrangement(s) over the long term" to do it.... you have a much larger problem to deal with

I saw a Fav lady...  one of my first...  monthly (more or less) for the first year...  then she started taking short cuts & rushing.  I took a year off from her (she thought I was never coming back) & found a couple more Favs.  I went back to her but only in a loose rotation with other Favs.  She had begun rushing & shortcutting and cutting out services I expected to be included in her bonus rate (I bumped it up in the past & if I went back to her original rate, I'm sure she'd be furious...  but that's where the services are now.)  I have just ended it...  after 6 years...  because she went ballistic on me for a misunderstanding which was mostly her fault & lack of communication on her part.  I'm going to miss her, but "know when to fold 'em, know when to walk away..."
It is pleasant to have Favorites who we get to "know" some...  but I will never go "exclusive" with one gal...  remember she's not being exclusive with you!

The sooner you realize that the better.  This whole "ATF" thing should be replaced by "ATM" in all mongers minds and things would be better for both parties. I plead guilty to the same thinking. As has been said many times. For a reality check just ask for some "OTC" time and you will understand where things really are. Been there. Done that. And it works!

You feel taken advantage of. You can't keep your schedule open at all times just in case she reschedules. Even if it is open, I think you feel you need to put your foot down.

I would say go with your gut instinct. Just find the best way to quickly and easily say "let's just reschedule when your schedule will allow you to keep the time planned."

If she is cool, she'll get it. If not, remember you didn't join the party here to deal with chaos. You came for relief.

If it doesn't bother you, try to work something out with her. But if it does, maybe find someone else until her schedule calms down a bit. She could be taking on other responsibilities that are affecting her here.

The thing that irks me is how after a few times the gal seems more interested in just hanging out and talking rather than activities.  

I just stop seeing them for a while and then when I finally do see them again after several months, I find that there service has gone back to the original get-up-and-go.

Try that and see how it works.

By the way, up in New Hampshire, the Old Man in the Mountain was taken for granite and look what happened to him:

she gonna have u doing errands next .. find more

favorite girls to see.. its that simple ...and shell miss your $$$$$$$$$$$$$$$$$$$$$$$$$ ....

She's getting exactly what she wants

And you're allowing it.

She's not your GF...she's a hooker seeking to get paid to perform sexual activities.  Don't lose sight of why you are here...how you met her.

The arrangement is a very simple one...you call and set up a time.  She either agrees to see you then or not.  And if it's for 2 hours (or 3 or 4...and so on)...it's your dime.  If she needs to leave early then she shouldn't have agreed to fuck you for the time you scheduled for.

Lay it out in those terms...and either she'll get that you are not a dude who will pay someone to NOT provide a service, or she won't and you can then move on to one who is happy to do what you are seeking.

Don't make this complicated...it shouldn't be.

Ditch the bitch. Eight months is a long time. The thrill will soon be gone. Congratulations on finding a lady that you like that much. Remember, love ain't on the menu.

Consider asking if everything is OK? You ask because of the reasons you stated. If you do ask, and you ask without implying anything, ignoring your feeling of being taken for granted, you will gain more information which may help you grasp the situation better.

If your objective is to establish a long term mutually beneficial arrangement, the best arrangements are ones where exactly what is beneficial for each party is understood.  Sometimes, writing down what constitutes what each party wants to receive helps provide a stable base, and can reduce mus-understandings when people use the same or similar words but attach different meanings to them.

Be alert for indications of someone who isn't comfortable stating their expectations, wants, needs etc.

Also be alert for symptoms of my biggest downfall, wanting people to be the way I want them to be rather than accepting them for the way they are.

Above all, have you discussed if she wants to work towards or establish a long term relationship?

Currently, I'm very thankful I do not have to worry about issues like those. The last three years of my wife's life she endured constant pain, dealing with it by taking increasing amounts of pain meds to dull the pain. I had to take care of her,, carefully monitor insurance co, hospital staff, testing staff, pharmacies, Dr's offices to insure that when they failed to do what they were supposed to do that my wife didn't have to suffer.  It was constant high STRESS!! We became very, very, very close. I held her as she died in my arms in a hospital room.

I just do not have any desire for working through problems right now.

Deprived

you should always let performance for your dollar dictate your choices -  

repeating with a provider you enjoy can result in increased performance as she gets to know your responses and if she cares about you as a client -

repeating too much will result in a decline - in being taken for granted

when you see that you are being taken for granted you need to either move on or take a break,  and if you start up again,  reduce frequency considerably -

oftentimes if you take a break it will be resented - if you see any sign of this then you know that you were entirely taken for granted and that there is no sense in trying to continue the situation

if she takes the hint by ramping up the performance when you revisit then the lesson was learned -

in any event,  I think you will find that no more than 4 to 8 visits a year is appropriate in most cases...

Wow! So many warm stories of LTR and "friends" on this thread!

What do these friendships consist of? You like the same music? The same comedians? Same political views?

When the authorities come, will you hide your friend?

Will he or she hide you?

What guales determine friendship for you folk?

My guess is that the Provider I'm seeing does not. She never has rescheduled our meetings. I can usually see her anytime I want.  

I would give her another chance. She probably had a busy day when you called her.

Thanks everyone for replying. I appreciate all the feedback. At a minimum I do think we need to have a conversation concerning my expectations of her and her expectations of me going forward and see were that leads. I probably just needed to vent a little bit in the moment and hear from others what I already knew.

trying to take advantage of you.

it has to be more than the one instance.

She has something going on in her life that is causing a time crunch or issue.  It may be personal and not something she feels comfortable sharing
