Could be paranoia on your part, or could be nothing at all. If it is really bothering you then I would suggest waiting it out.

1. BFM, they had a visit from the leo, most likely nothing to worry about, look how many indie's have had leo visits in the last year or 2, Not many, and if you notice agencies are getting the visits, since they are easier to trace.  

2. Numbers change all the time, not a big deal.  

3. As for moving the appointment, maybe she already had one and wants some extra time to get ready for yours.
or she doesn't like to see guys before 1.  No big deal.

4. Really she doesn't call you sugar any more and you worried about. Your really being paranoid.  

Look you said she was your favorite and you haven't seen her in in awhile, so she many have forgot somethings about you.
When she see's your face, maybe things will come back to her about you, and she will call you sugar. Remember these ladies see and communicate with lots of guys, they are not going to remember everything about every guy they have seen.  

Go see her, and have a good time

It is said "perception is projection" and  because something is our perception doesn't make it real.

Of course the counter to that is: " Just because you're paranoid, doesn't mean they are not out to get you."

Your asking here appears to be an attempt to find some reasonability or balance in all this. Not that it matters what I think,  it is a wise thing to do.  I wish I could say hey, dude your whacked, but I can't just as I can't say you're right.

However, lets look at his and break it down.

2) You're not a provider, you're not on our side of the line so you are going with how YOU think it works. Sorry, but her prime hours and another providers prime hours  may not be the same. On this one, I do think you're reaching definitely.

3) You forgot it.

4) Human beings are pattern creatures. This is what makes us relatively predicable. As a rule, we don't break patterns without a reason. Therefore, is this pattern change about you or something else? We don't know, however you're speculating it's business related. For all we know she has a new Boyfriend or Girlfriend and it has changed her base emotional state. I see it happen all the time not only with my associates but a few independents I'm BFF with as well.

As for Tysons, I suspect based upon everything you've stated you suspect or perceive if she said BWI, you'd still be writing this post.

 You could also  get you're own room and request an outcall thereby eliminating some of the variable out of your control.

Bottom line, follow your gut and accept there is a good chance you are completely wrong.  Take a deep breath and trust yourself, just guard against being crazy and reacting to things which may not be there.

I wish I could offer you something more definitive.

A simple phone call should solve it for you.

If you don't feel it's right - cancel and don't go through with it

Paranoid

Not at all. If you were a caveman and saw a buddy get eat by a lion when out hunting. You'd know the signs from when it happened. If you'd head out and notice those signs a tingle would go up your back and you would say "I'm getting ready to get ate by a Lion".  That toggle will save your ass.

If you have a bad feeling it isn't worth the embarrassment that getting arrested will bring you and your family. Depending on what you do an arrest could effect your job, you security clearance, your marriage!  

Just run for the hills if you have the slightest doubt!
