I think it' possible he does not yet know how to handle a highly motivated, goal-oriented blunt client. As you've pointed out, he likely deals with a very different population.
I feel professionals should know some about fibromyalgia in 2018. This is a prevalent condition. It has been in various types of headlines since the 1980's as fibromyalgia ( and before that as "fibrositis.") It would not take much to gain an understanding before a second appt, as there is now so much info readily available. I also feel he should have a better overall understanding of you if he has read Richard's summary. Yes, he may have wanted to hear from you.
Is he a "trauma therapist?" I hope so.
I feel a 3 month trial is very generous on your part.
I'll admit this is a touchy topic for me, as my long-term pdoc (he is also my therapist) is retiring in May and I cannot see anyone truly measuring up to him.
I hope this therapist comes through for you! You deserve a good break, as in ease from here on out!
